I Was Marked By The System's Arbiter

Chapter 118: Chapter 118: Someone in the Window

The third floor was brighter than any part of Yinshan Academy had a right to be.

After the gray murk of the Old Library, after the shelf of forgotten names and the child’s voice counting them in the dark, the ordinary daylight spilling through the third-floor windows felt almost offensive. Lin Yue stepped off the stairwell and had to blink against it, the way a person blinked stepping out of a matinee into afternoon sun.

"Okay," Shen Rui said, dragging a hand down his face. "This is either a very good sign or a very bad one. I genuinely don’t know which anymore."

"It’s neither," Su Qing said. "It’s a hallway. Try not to read prophecy into architecture."

"After last night, I’m reading prophecy into everything. I read prophecy into my own shoelaces this morning."

Nobody laughed, but Tang Li’s mouth twitched, which was as close to laughter as any of them had managed since the library.

The corridor ran long and pale, lined on one side by a row of tall windows that looked out over the academy’s inner courtyard — gray sky, wet stone, the same soft rain that never seemed to make a sound wherever they went. On the other side, classroom doors stood shut in careful, even intervals, brass numbers polished to a shine none of the lower floors had bothered with.

"Ordinary," He Yuan muttered, like he didn’t quite trust the word even as he said it. "This looks ordinary."

"It’s supposed to," Lin Yue said. "That’s usually when it isn’t."

He didn’t say it to frighten anyone. It came out flat, more habit than warning, the same way a person might mutter watch your step over dry pavement out of nothing but reflex. But He Yuan’s shoulders drew up anyway, and beside him, Mo Jun said nothing, only shifted half a step closer, an adjustment so small it barely qualified as movement.

Lin Yue noticed it. He noticed most things that repeated.

They walked the corridor in a loose cluster, footsteps swallowed by a carpet runner the color of dried blood, faded to rust by years no one alive remembered. Halfway down, Bai Wuyin’s small hand found the hem of Lin Yue’s sleeve, the way it always did in front of the others — not gripping, just resting there, a boy keeping himself tethered to the one adult he trusted.

It was Lin Yue who noticed the windows first.

Not because anything was wrong with them. Because nothing was.

"These are clean," he said.

Su Qing glanced over. "That’s a problem now?"

"Every other window in this school has had rain on it that doesn’t fall the way rain should. Streaked. Fogged in patches. Wrong in a dozen small ways." Lin Yue slowed, studying the glass as he passed each pane. "These aren’t spotless. But they’re clean enough that I can see myself in them clearly. That’s new."

Shen Rui squinted at his own reflection in passing, tugging at his collar. "I look like garbage. Can confirm the glass works."

"That’s not what he means," Tang Li said.

"I know. I’m coping."

Lin Yue kept walking, kept looking, the reflex too old now to switch off even when nothing seemed to be asking for it. His own reflection kept pace with him, gray-lit and unremarkable. Beside it, a step behind, Bai Wuyin’s small shape trailed along the glass exactly the way it should — head down, sleeve gripped, the picture of a frightened child sticking close to the only person he trusted.

Then Ning Yue’s reflection passed into the same pane, notebook tucked under one arm, and for one full breath, everything in the glass matched everything in the hallway, person for person, shadow for shadow.

Then it didn’t.

Lin Yue’s steps slowed without his telling them to.

There was one more person in the window than there was in the corridor.

He didn’t say anything at first. He did what he always did before he trusted a thing enough to name it — he checked it twice.

He looked at the reflection. A girl’s silhouette, standing near the far end of the window’s reach, close to where the glass met the wall. Long hair, or something that read as long hair in the dim reflected light, hanging forward past where a face should have been visible. A school uniform, the pale collared kind every ghost student in this academy seemed to wear without exception. Her head was lowered, chin nearly to her chest, and she did not move. Not a sway, not a shift of weight, not the small unconscious motion every living body made even standing perfectly still.

He looked at the corridor.

Nothing. No girl. No shadow cast on the floor that could account for her. No door nearby she might have stepped out from.

He looked back at the glass.

She was still there.

"Lin Yue?" Su Qing had noticed him stop. "What is it?"

He didn’t answer immediately. He crossed to the window instead, close enough that his own breath fogged a small patch of the glass, and studied the reflection with the same patience he’d given the shelf of forgotten names the night before.

"There’s someone in the window," he said finally. "There’s no one in the hallway."

That got everyone’s attention at once.

Shen Rui was the first to move, predictably, stepping sideways along the corridor like a man testing a floorboard he didn’t trust. "Where? I don’t— wait." He froze mid-step. "Okay. I see her. I see her now. Why didn’t I see her a second ago?"

"Because you weren’t looking at the right angle," Su Qing said, already moving with a very different kind of urgency — not toward the window, but along it, testing rather than approaching. She shifted three steps to the left. The silhouette remained exactly where it had been, unmoved, as though the window itself had not shifted with her at all. She shifted back, then further right, past where Lin Yue stood.

"She’s not tracking us," Su Qing said slowly. "A reflection should move relative to the viewer. Every reflection in this hallway does — mine does, yours does. Hers doesn’t. She’s fixed."

"Fixed to what?" Tang Li asked. "The glass, or the wall behind it?"

"I don’t know yet." Su Qing crossed to the next window down, four panes away, and looked in. "She’s not here. Only in the first window." A pause. "No — wait." She checked the next one after that. "Here too. Different window, same position relative to the frame."

"That’s not how reflections work," He Yuan said, voice climbing half an octave. "That’s not — reflections don’t relocate themselves between panes of glass that aren’t even connected—"

"Nothing here works the way it’s supposed to," Su Qing said, not unkindly. "You knew that yesterday."

"Knowing it and watching it happen in front of me are different things!"

Mo Jun’s hand found He Yuan’s shoulder, light, brief, grounding. "Look at me instead of the glass for a second," he said, low and even. "Breathe. In for four."

He Yuan obeyed almost before he’d decided to, dragging in a shaking breath that evened out half a second later. Su Qing’s eyes flicked toward Mo Jun, then away, filing the moment somewhere behind her expression without comment.

Lin Yue kept his attention on the girl.

She had not moved a single fraction the entire time they’d tested her, not toward them, not away, not so much as a tremor. Whatever she was fixed to, it wasn’t the group.

"She’s not facing us," he said.

Everyone turned toward him.

"Look at her shoulders. Her head’s down, but her body’s angled." He nodded toward the glass without pointing, an old habit — pointing drew attention the wrong way, sometimes literally, in a place like this. "She’s facing outward. Toward the courtyard. No — past the courtyard."

Su Qing tracked the angle, following an invisible line from the silhouette’s shoulders outward through the glass, out past the wet stone courtyard below, toward the low gray shape of a building visible past the academy’s outer wall.

"That’s the dormitory block," she said quietly.

The corridor went very still.

"Why would a reflection care what direction it’s facing?" Shen Rui asked, and for once there was no joke tucked into the question at all.

"I don’t know," Lin Yue said. "But it isn’t looking at us. It hasn’t looked at us once."

It was Ning Yue who broke first — not because she was careless, but because she had spent the entire previous night writing down everything she could measure, distrusting her own memory more with every page, and some very small, very human part of her had simply run out of patience for standing still in front of an unexplained thing and doing nothing about it.

She’d drifted a few steps closer than the rest, notebook open, pen hovering, already sketching the silhouette’s proportions in the margin the way she’d sketched the shelf’s eight sections the night before. Head lowered. Hair past collarbone, no visible face. Facing—

The silhouette raised one hand.

Ning Yue’s pen stopped mid-stroke.

"Did anyone else—"

"I saw it," Su Qing said immediately, sharp. "Don’t move."

The hand hung there, half-lifted, fingers loose, the posture unmistakably, achingly human — the small, tentative motion of someone unsure whether a wave will be returned.

"It could be a distortion," Ning Yue said, more to herself than anyone. "Light does strange things through old glass. It could just be—"

The fingers curled, then opened again. Slow. Deliberate.

It was a wave.

Nobody told her not to. Nobody told her to. That was the thing Lin Yue would turn over later, again and again, trying to find the exact half-second where the mistake had actually happened — because there hadn’t been one. Nobody had encouraged her. Nobody had warned her fast enough. She simply reacted the way any person raised among other people reacts when something waves at them from across a room.

Ning Yue raised her hand and waved back.

For one full second, nothing happened.

The corridor held its breath along with her. The rain streaked silently against the glass. The silhouette stood exactly as it had, hand still raised, mirroring nothing, answering nothing, and for that one endless second Lin Yue thought, with something close to relief, maybe it really is only light.

Then the silhouette lowered its hand.

"See?" Shen Rui said, a little too loud, a little too fast, the words tumbling out on a breath of released tension. "Nothing happened. It’s just — it’s some old projection thing, some leftover — nothing happened—"

Ning Yue lowered her own hand a beat later, already turning back toward her notebook, already reaching for the version of this where it had been nothing at all.

Lin Yue didn’t move.

He was watching the window, not the group, and what he’d seen sat wrong in a way he couldn’t yet put a clean sentence to.

"Lin Yue?" Bai Wuyin’s small fingers tugged once at his sleeve, the frightened-child pull, but the eye that looked up at him — just one flick, quick enough that no one else caught it — held nothing frightened in it at all.

"It didn’t lower its hand with her," Lin Yue said quietly, for Bai Wuyin alone. "It lowered it after."

"How much after?"

"Less than a second. Enough to notice. Not enough to explain away."

Su Qing had drifted closer, close enough to catch the tail end of it. "After what?"

"After Ning Yue," Lin Yue said, louder now, so the rest of the group could hear. "It didn’t move with her. It moved because of her. There’s a difference."

"That’s — that’s a stretch," Shen Rui said, but his voice had gone thin again, the relief from a moment ago already curdling.

"Maybe," Lin Yue allowed. "But a reflection copies instantly. A person copies with a delay, because they have to notice the gesture first before they return it." He looked at the window one more time. The silhouette stood exactly as it had before Ning Yue had ever raised her hand — head down, unmoving, facing the dormitory. As though nothing at all had passed between them.

As though it were only waiting to be looked at again.

"Let’s keep moving," Su Qing said, and there was no argument from anyone.

Bai Wuyin waited until the group had rounded the next corner, until the chatter of Shen Rui trying too hard to sound normal had put enough distance between them and Lin Yue that no one would think to look back, before he tugged Ning Yue gently by the sleeve of her cardigan and drew her half a step out of the group’s path, toward the mouth of a side stairwell.

In front of everyone, his voice still carried the small tremble it always did. "Um — Sister Ning Yue? Can I— can I ask you something?"

Ning Yue blinked down at him, some of the tension in her shoulders easing at the sight of him — twelve years old, wide-eyed, harmless. "Of course. What’s wrong?"

He waited until the last of the group’s footsteps had faded around the bend.

Then his voice dropped, and every trace of the tremble went out of it at once.

"Don’t acknowledge it again," he said. "It’s counting how many times you do."

Ning Yue’s smile faltered. "...What?"

"The girl in the window. Don’t wave at her again. Don’t nod. Don’t even hold eye contact with the reflection longer than you have to." His single visible eye — the sharp, ink-black one — held hers without a trace of the fear he wore for everyone else. "You already gave her one. Don’t give her a second."

"Bai Wuyin, I—" Ning Yue’s mouth worked for a second, caught between the child she’d been comforting a moment ago and the person now standing in his place. "Counting what, exactly?"

"I don’t know the word for it yet." He said it plainly, without apology, the way Lin Yue might have. "But I watched her posture change after you waved. Not much. If you weren’t looking for it, you’d miss it completely. Her shoulders came up, just slightly, the way someone’s do when they’ve noticed they’re not alone anymore. That’s not what a projection does. Projections don’t notice things."

"You think it recorded me."

"I think it recognized you," Bai Wuyin said. "That’s worse."

Ning Yue’s hand tightened around her notebook. "Recognized how? I didn’t say anything. I didn’t tell it my name—"

"You don’t have to say your name for something to know who you are." His voice had gone very quiet, very steady. "You answered it. That might be all it needed."

"It was a wave," Ning Yue said, and for the first time some of the fear she’d been holding back for hours cracked through into her voice. "It’s not even a word. It’s not a real answer to anything—"

"I don’t think that matters to it." Bai Wuyin glanced once toward the corner the group had disappeared around, then back to her. "I think it’s counting acknowledgments. Not questions and answers. Just — being noticed. Being seen and seeing back. You did that. Once."

"...Once," Ning Yue repeated slowly, like she was trying to convince herself the number meant something small.

"That’s why we don’t give it another," Bai Wuyin said. "Whatever it wants from you, it only gets more of it every time you let yourself be seen seeing it. So don’t." His hand found her sleeve again, small and light, the picture of a frightened child needing comfort — except his eyes, just for that moment, held none of that fear at all. "Please. I mean it."

Ning Yue looked down at him for a long moment. Then, slowly, she nodded.

"Okay," she said. "Okay. I won’t."

It was only once they’d caught up to the others — Bai Wuyin’s shoulders curling back inward, his voice climbing back into its practiced tremble, asking Shen Rui in a small, worried tone whether they were going to be late for the next class period — that Lin Yue fell back half a step to walk beside Ning Yue.

"He told you something," Lin Yue said. Not a question.

Ning Yue hesitated only a second before nodding once, tightly.

"How many?" Lin Yue asked.

"...One," Ning Yue said. "He said I gave it one."

Lin Yue didn’t ask one what. He already understood the shape of it well enough not to need the word spoken aloud, and saying it out loud, here, in a corridor lined with clean glass and rain that made no sound, felt like exactly the kind of thing that would make it truer.

"Then that’s the number we work from," he said instead, quiet enough that only she could hear. "Don’t let it become two."

It became clear within the hour that the number had already stopped being something Ning Yue could control simply by refusing to look.

They passed a classroom window on the way to the stairwell, and Su Qing froze mid-sentence, her gaze snapping past Ning Yue’s shoulder to the glass behind her.

"Don’t turn around," Su Qing said, very carefully. "Just — don’t turn around yet."

Ning Yue’s whole body went rigid. "Is she there?"

"She’s there."

Tang Li had already stepped closer to look, and her face changed the moment she did — not fear, exactly, but the particular unease of watching a pattern confirm itself. "I don’t see her in the reflection near me. Or Shen Rui. Or Lin Yue." She swallowed. "Just behind you, Ning Yue. Only behind you."

Ning Yue turned, slow, and looked.

There she was. The same lowered head, the same still hands, the same lifeless hang of dark hair. Standing several steps behind Ning Yue’s own reflection in the glass, facing the same direction as before — not toward Ning Yue, not toward the group, out past the frame of the window entirely, toward wherever the dormitory sat beyond the wet stone courtyard.

"She’s not in the corridor," Lin Yue confirmed, checking behind Ning Yue with his own eyes, finding nothing but empty hallway and afternoon light. "Only in your reflection."

"Try another window," Su Qing said. "Different hall, different glass. If this is tied to the location, it’ll stop."

They tried. A stairwell window three floors down showed the same silhouette, positioned the same distance behind Ning Yue’s reflected shape, facing the same unbending direction. The library’s high arched window — glimpsed only briefly, none of them eager to linger near that room again so soon — showed her too, further back this time, half-swallowed in shadow, but there.

By the time they reached the cafeteria for the midday meal, nobody bothered testing anymore. They simply avoided glancing at the long windows lining the west wall, and Ning Yue kept her back deliberately to the glass the entire meal, picking at food she didn’t eat.

"It’s not attacking her," He Yuan said quietly, more to reassure himself than anyone else. "It’s just — standing there. That’s all it’s done. Just stood there."

"So far," Su Qing said.

"That’s not comforting, Su Qing."

"I wasn’t trying to be."

Lin Yue said nothing for a long moment, turning the shape of it over the way he turned everything over before letting himself trust a conclusion.

"It’s never faced her," he said finally. "Not once. Every window, every angle — it faces the dormitory. If it wanted Ning Yue specifically, wouldn’t it look at her? Wouldn’t it want to be looked at back?"

"Maybe it already got what it wanted," Su Qing said. "One acknowledgment. Maybe that’s the whole transaction, and now it’s just... attached. Like a shadow that picked a person to follow."

"Then why does it keep looking somewhere else?" Lin Yue asked, and no one at the table had an answer for him.

The System found its moment that evening, in the quiet stretch of hallway between the dining hall and the dormitory block, when the light had gone the color of old bruises and the rain-that-made-no-sound had finally, mercifully, stopped streaking the glass at all.

Ning Yue heard it first — not the System, but something smaller, something that made her stop dead in the corridor and grip her notebook hard enough to crease the cover.

A voice from the window beside her. Faint. Almost polite.

Do you remember my face?

She didn’t answer. She’d promised Bai Wuyin she wouldn’t, and some instinct older than the promise kept her mouth shut tight even as every part of her wanted to turn and look.

Blue light bled into the edges of the corridor a heartbeat later, cold and clinical, exactly the way it always did when the academy had decided something needed to be made official.

[RULE UPDATE.]

[RULE 04 — NEVER ANSWER QUESTIONS FROM SOMEONE WHOSE FACE YOU CANNOT REMEMBER.]

The words hung there, and beneath them, a second line resolved slowly out of the same cold light.

[ACKNOWLEDGMENT DETECTED.]

[SUBJECT: NING YUE.]

[STATUS: RECOGNIZED.]

Ning Yue’s breath caught audibly. Shen Rui swore under his breath. Even Su Qing, who had not so much as flinched at the empty desk or the eight sections of forgotten names, went very still.

A final line surfaced, slower than the rest, as though the System wanted to be certain it was read in full before it let the light fade.

[CONNECTION ESTABLISHED.]

Then the corridor dimmed back to its ordinary evening gray, and the System said nothing further.

"That’s it?" Shen Rui said, into the silence that followed. "That’s the whole rule? We don’t even get told what it means—"

"It didn’t answer a spoken question," Lin Yue said slowly, working through it out loud, the pieces settling into place one at a time. "She didn’t say a word to it. She waved."

"So?" He Yuan’s voice had gone thin again.

"So the Rule doesn’t say never speak to someone whose face you can’t remember. It says never answer." Lin Yue looked at the window, at his own faint reflection in the darkening glass, undisturbed, ordinary. "A wave is an answer. The academy’s definition of answering something is broader than words. It always has been. We just hadn’t been asked the right question yet to notice."

"That’s — " Tang Li’s voice wavered. "That’s an insane standard. How is anyone supposed to follow a rule like that if just waving counts?"

"By remembering the face first," Lin Yue said. "That’s the actual condition. Not don’t answer. Don’t answer someone whose face you cannot remember." He turned to Ning Yue. "What did she look like?"

Ning Yue opened her mouth automatically, the reflex of a person used to being asked and used to having the answer ready.

Nothing came.

"She had — " Ning Yue frowned, reached for it, found the reach coming back emptier each time she tried. "Long hair. The uniform, the same as the others. Her head was down, so I don’t— I didn’t see her face directly, but I should still remember the shape of it, shouldn’t I? A jaw. A nose. Something." Her fingers had gone white around her pen. "I can’t. I can picture the hair. The hands. The way she stood. I can’t picture her face at all. I don’t think I ever actually saw it. But it doesn’t feel like something I missed. It feels like something that isn’t there to remember."

"That’s the condition," Lin Yue said quietly. "Not that her face is hidden. That it can’t be held onto at all. Every time you try, your memory refuses to keep it."

The corridor had gone very quiet.

"So the Rule isn’t don’t answer ghosts," Su Qing said slowly, understanding arriving in her voice a half-second behind the rest of her. "It’s don’t answer anyone your mind won’t let you remember. That’s not the same warning at all."

"No," Lin Yue agreed. "It’s a much narrower one. Which means it’s not describing every ghost in this school." His eyes moved, unbidden, toward Mo Jun, who stood a careful step behind He Yuan’s shoulder, face composed, saying nothing. "It’s describing a very specific kind of thing that can be standing right in front of you and still leave nothing behind for you to hold onto."

Mo Jun met his gaze without flinching, and said nothing at all — which, in its own quiet way, answered more than words would have.

They reached the dormitory corridor a little after full dark, and it was Su Qing, walking last, who finally said what half the group had been carefully not saying since the cafeteria.

"You’ve been doing that a lot," she said to Mo Jun, low enough that only those nearest caught it. "Knowing what He Yuan needs before he says anything’s wrong."

Mo Jun glanced at her, unhurried. "Is that a complaint?"

"It’s an observation." Su Qing’s voice stayed level, careful, the same tone she used for measuring reflections. "Breathe in for four. Look at the floor. Count the spaces between the doors. You said all of that today before he even told you what he was looking at."

"He gets the same kind of frightened every time," Mo Jun said. "It’s not difficult to predict."

"That’s not an answer to how you know what to say. That’s an answer to why you don’t think it’s strange that you do."

Mo Jun was quiet for a moment, and something passed briefly over his face that Lin Yue, walking just ahead, caught only the edge of — not guilt, exactly. Closer to the look he’d worn in the library doorway, gazing toward some point deeper in the room none of them could see.

"I don’t know," Mo Jun said finally, and for once there was no easy warmth folded into it, no teacherly reassurance. Just the plain, uncomfortable shape of the truth. "It just seems obvious. Like something I already know, and I’m only remembering it, not learning it fresh."

Su Qing studied him a long moment.

"To you," she said quietly.

Mo Jun didn’t answer that either. He only turned back toward He Yuan, who was already glancing at the dormitory windows with visible dread, and said, low and steady, "Look at me instead. We’re almost there."

Su Qing said nothing further. But Lin Yue saw the way her eyes stayed on Mo Jun’s back the rest of the walk, and filed the shape of it carefully away, beside everything else about the man that fit too well for someone who claimed to remember none of it.

Room 205 was quiet when Ning Yue finally shut the door behind her, and for a while, quiet was all it was.

He Yuan had gone to wash up down the hall, promising to be back within the quarter hour, and Ning Yue used the solitude to do the only thing that still felt like solid ground beneath her — she opened her notebook, uncapped her pen, and began writing down everything the day had given her while it was still fresh enough to trust.

Window 1 — silhouette present. Facing dormitory.

Window 2 — present. Same orientation.

Window 3 — present. Farther back in frame.

She hesitated over the fourth line, pen hovering, and found herself unable to finish the sentence the way she’d started it.

It appears only when I look—

She crossed it out. She wasn’t sure that was true. She wasn’t sure of anything about it anymore, and that uncertainty itself felt like the most honest thing she’d written all day.

The curtains were already drawn. She’d drawn them herself the moment she’d stepped inside, before even setting her bag down, and she didn’t examine too closely why that had felt necessary.

For a while, nothing happened at all. The dormitory hallway outside was silent in the ordinary way, footsteps distant, a door closing somewhere down the corridor, the small, unremarkable sounds of other players settling in for the night.

Then, from just outside Room 205’s door, a voice spoke her name.

"Ning Yue?"

Her pen stopped.

It was quiet. Familiar. Almost casual, the way a friend might call through a door before knocking, not wanting to startle her.

It was her own voice.

She sat perfectly still, notebook open in her lap, and told herself, very deliberately, that she had imagined it. That the day had worn her down to the point where her own mind was playing tricks with sound and memory both.

The voice came again, exactly as before — her cadence, her breath pattern, the small habitual lift at the end of a question that she’d never once noticed in her own speech until she heard it now, from outside a door, addressed to her.

"Are you there?"

She did not answer. Bai Wuyin’s warning sat in her chest like a stone, heavier now than it had been that afternoon. Don’t acknowledge it again. She pressed her lips together and did not make a sound, did not so much as shift her weight on the bed, as though stillness alone might convince whatever stood outside that the room was empty.

The hallway went silent.

For one long, breathless stretch, she thought that might be the end of it — silence, and then nothing, and then morning.

Then, softer now, almost intimate, as though it had leaned close to the wood of the door to say it:

"It’s me."

Ning Yue’s breathing stopped entirely.

She knew she hadn’t said that. She knew, with absolute, bone-deep certainty, that she had never once in her life said those two words in that exact tone, standing outside a door in the dark. And yet it was her voice all the same, unmistakably hers, carrying itself through the wood with none of the distortion a copy should have.

Something that might have been laughter followed — soft, almost fond, the kind of low exhale a person makes remembering something pleasant. Or perhaps it was only breath, shaped by something that had learned the sound of laughing without ever quite understanding what it was for.

Then, quieter still, almost gentle:

"You waved at me."

Ning Yue did not move. Did not breathe. Did not let the pen in her hand so much as tremble against the page, though everything in her wanted to shake apart at once.

The silence stretched on, long enough that she almost believed it had finally gone.

Then, one last time, drifting through the door like something spoken directly against her ear, patient and terribly, terribly calm —

"Why won’t you wave again?"
