By the time the final bell rang, the world had already gone back to pretending nothing was wrong. Which was impressive, considering it never stopped being wrong. I packed my bag slower than usual, not because I had nothing to think about—but because I had too much. The kind of thoughts that don't form properly, just sit there, heavy, like unfinished sentences.
A girl who fades from memory. No—worse. A girl people don't even realize they've forgotten.
"…Observer, huh."
I muttered it under my breath and stood up. No one reacted. Of course they didn't.
The hallway was crowded, loud, normal. Too normal. Students talked, laughed, complained about homework like their lives depended on it. Someone dropped a pen. Someone else cursed. A group of girls walked past me, whispering and giggling like the world wasn't quietly breaking in the background.
And right in the middle of all that—she was there.
Leaning against the wall. Alone. Completely untouched by the noise around her.
Sakata Setsuko.
I walked up to her, stopping just close enough that it felt intentional. "You waited."
She glanced at me, her expression softening just slightly. "You came back."
"Didn't have anything better to do."
"That's a lie."
"Yeah."
She smiled faintly. For a moment, neither of us said anything. The crowd kept moving around us—no, through us. Not physically. But in a way that made it obvious we didn't belong in the same version of reality as them.
I noticed it again. That subtle distortion. The space around her felt… delayed. Like if you reached out, your hand wouldn't quite connect where it should.
"Walk with me," she said.
She didn't wait for an answer.
We moved through the hallway side by side. Or at least, I moved. She… drifted. There was no other way to describe it. Her steps were real, but the floor didn't quite acknowledge them, like she was walking on something slightly out of sync with everything else.
"You're staring again," she said.
"I'm observing."
"That sounds worse."
"It's more accurate."
She huffed softly, but there was no real annoyance in it.
"You said it's been five months," I continued. "Since this started."
"Yes."
"And it's getting worse."
"…Yes."
Her voice dropped slightly on that one. Not fear. Something quieter than fear. Acceptance.
I didn't like that.
"So what changed?" I asked. "People forgetting you isn't exactly something that just stabilizes."
She stopped walking. I took another step before realizing she wasn't beside me anymore. When I turned back, she was standing there—perfectly still.
And for a second—
She flickered.
Not visually. Not like a glitch you could point at. It was worse than that. My brain just… failed to confirm she was there. Like reality skipped her for a moment and then corrected itself.
"…You saw that, didn't you?" she asked.
"Yeah."
"Good," she said softly. "That means it's getting worse."
I stared at her. "That's your definition of good?"
"It means I'm not imagining it."
"You are the problem," I said flatly.
She smiled. Not offended. Almost relieved.
We ended up back at the balcony. Same place. Same wind. Different feeling.
This time, I paid attention.
The railing. The floor. The shadows. Everything was normal.
Except her.
The wind passed through her hair—but not quite the same way it passed through mine. Like it hesitated. Like even the air wasn't sure how real she was.
"…Try something," I said.
She glanced at me. "What?"
"Touch the railing."
She blinked, then stepped forward. Her fingers reached out slowly, carefully—like she already knew what would happen. They made contact.
Kind of.
There was a faint delay, like her hand arrived a fraction of a second before the world allowed it.
Then—
A thin trail of smoke curled up from where her fingers met the metal.
She flinched and pulled back. "…It burns."
"Metal doesn't just burn people."
"It's not the metal."
"…It's reality rejecting you."
She didn't respond. Which meant I was right.
I leaned against the railing, crossing my arms. "So let me get this straight. You had a thought—what if I disappeared—and now reality is slowly making that happen."
She nodded.
"And the more time passes…"
"The less I exist."
I exhaled slowly. "…That's annoying."
She blinked. "That's your reaction?"
"What do you want me to say? It's not like I can punch the problem."
"You'd try, wouldn't you?"
"Depends on how annoying it gets."
That earned a quiet laugh. Short. Soft. Real. And for a moment, she felt completely normal.
"…Why didn't you fight it?" I asked.
She tilted her head. "Fight what?"
"This." I gestured vaguely at her entire existence. "You said you got used to it."
"I did."
"That's the problem."
She looked at me, confused.
"You're disappearing," I continued. "And instead of resisting it, you adapted. That means part of you accepted it."
Her expression shifted. Just slightly.
There it was.
I stepped closer.
"You said your fans need you. You said you'd never disappear."
"I—"
"But you still thought about it."
Silence.
The wind picked up, pushing her hoodie back slightly.
"You wanted to disappear," I said quietly. "And you didn't."
She looked away. "You don't understand."
"Then explain it."
She was quiet for a long time. Long enough that a normal person would've filled the silence. I didn't.
"…It wasn't like that," she said finally. Her voice was softer now. Less composed. "Everyone saw me. Everywhere I went. Cameras. People. Expectations."
Her fingers curled slightly.
"But none of them… actually saw me."
I didn't interrupt.
"You know what it's like," she said. "Being surrounded by people… and still feeling invisible?"
I looked at her. Really looked this time.
"…Yeah."
That was enough.
She smiled faintly. Sad.
"So when I thought about disappearing… it wasn't because I hated being seen." A pause. "It was because I was tired of being seen wrong."
I exhaled slowly.
"…You wanted to be seen."
"But also disappear."
We stood there in silence. The wind moved. The world continued. Unaware. Unchanged. Lying.
"…So what now, Observer?" she asked, her voice returning to that calm, teasing tone.
I looked at her. At the way the world struggled to keep her in place. At the way she pretended she was fine.
"…Now," I said, "we stop you from disappearing."
She blinked. "…Just like that?"
"Yeah."
"That's your plan?"
"I'll figure out the details later."
She stared at me for a second. Then she laughed. This time, a little louder. A little more alive.
"You really are strange."
"I get that a lot."
"I'm starting to see why."
I turned toward the stairs. "Come on."
"Where are we going?"
"If this started five months ago, then there's a pattern. Places. Moments. Triggers."
She followed behind me, barely making a sound.
"You're going to investigate me?" she asked.
"I'm going to understand the problem."
"That sounds cold."
"It's efficient."
She smiled faintly. "…I think I like that."
As we walked down the hallway, a student brushed past me, muttering an apology before moving on. For a split second, their shoulder passed straight through her.
No reaction. No awareness. Nothing.
I glanced back.
She didn't say anything.
But her expression—
For just a moment—
Cracked.
And that's when I understood something.
This wasn't just about disappearing.
It was about being left behind.
By everyone.
Except me.
"Hey," I said.
She looked at me.
"You're not disappearing today."
She blinked. "…That's a bold statement."
"I don't make statements," I said. "I make observations."
She smiled. Soft. Fragile. Real.
And for now—
That was enough.
