Interlude: A Memory That Doesn't Belong

The sky in her dream was violet.

The kind of violet that only exists when the sun forgets to set and the stars forget to rise — that moment in between, where time folds in on itself and waits to remember how to move forward.

She was there again.

On the rooftop. Not the school’s, not the planetarium’s — just a rooftop. Wide. Empty. Somewhere between childhood and the end of the world. The wind carried the scent of books left out in the rain.

And he was there too.

Not Kazuki as she saw him now, not exactly. He was younger, maybe. Or older. It didn’t matter. He had the same eyes. The same silence. The same way of standing like he was listening to something only he could hear.

He held a paper star in his hand. It glowed faintly. Like it had something to say.

“Do you believe in remembering things that never happened?” she asked him.

He didn’t answer. Just opened his hand.

The star fell.

And before it could hit the ground, the world shimmered.

Now she was in a train car. Wooden floors. No windows. Just fog. Her shoes were wet, like she’d been running. She was wearing a uniform she didn’t recognize, holding a letter with no address.

Across from her, he sat again. Older this time. Hair a little longer. A scar across his cheek that wasn’t real yet.

“You wrote me a promise,” he said.

“I forgot what it was.”

“You said if we met again, we’d get it right.”

She looked down. The letter had vanished.

“I don’t know how to find you anymore,” she whispered.

He leaned forward. “Then don’t. Just wait.”

“Wait where?”

And then—

She was small.

Six? Seven?

Sitting in a garden made of white trees and gold grass. A boy ran by, laughing, dragging a kite behind him. She followed him until he stopped and turned.

Kazuki.

Exactly as he is now.

But neither of them knew their names.

He handed her a rock. Not a flower. Not a toy. Just a plain white rock shaped like a heart.

“You dropped this,” he said.

“I don’t remember ever having it.”

“You will.”

And then—

She woke up.

Back in the planetarium.

Notebook in her lap. Dust falling like snow through the faint light. The stars still on above, even though no one had touched the switch in years.

She blinked slowly.

Waited.

Kazuki would come.

She didn’t know how she knew.

But he always did.

Chapter 3: The Stars We Didn’t Name

The third time he came, he brought nothing but his silence.

Kazuki stepped through the planetarium door with careful hands, as if the moment might break if he moved too quickly. The air was cold again, not from the outside, but from the way memory lingered too long in old buildings.

She was there, as always.

Hoshina.

This time, her hair was tied loosely to one side. A new page was open in her notebook, half-filled with slanted lines that looked more like thoughts than words.

“You really keep coming back,” she said softly, not looking up.

“You don’t lock the door,” he replied, sitting beside her.

“You don’t ask questions.”

He gave a small breath of a smile. “You don’t give answers.”

“I don’t know them.”

She closed her notebook and laid it on her lap, hands resting over it like something fragile.

The room fell into that same quiet that only they seemed able to hear. A silence made of breathing, and tension, and understanding with no name.

Kazuki glanced up at the domed ceiling. “The stars... do you know them?”

“Not by name,” she said. “Only by feeling.”

He looked at her. “Feeling?”

She pointed upward without lifting her hand. “That one,” she said. “It always feels like it’s listening. And that one—” her fingers moved slowly “—feels like someone trying to forget.”

Kazuki followed her gaze. The stars above were just lights, programmed and plotted years ago by someone who probably never came back to see them again.

But with her, they felt alive.

“Do you know what your name means?” she asked suddenly.

“Kazuki?”

She nodded.

He thought for a moment. “Harmonic hope. Or peaceful radiance. Something like that.”

She tilted her head. “You know the exact meaning.”

“...I looked it up a long time ago.”

“Why?”

He didn’t answer right away.

“Because I didn’t feel like I was any of those things. I wanted to know what I was supposed to be.”

Hoshina was quiet for a moment, then said, “You feel like someone who lives on the edge of a story, but keeps refusing to fall in.”

He turned his head toward her. “And what do you feel like?”
