Minju had always noticed her.
Long before she met Haru, before she knew what it meant to be truly lonely, the girl in the red cap had already been there.
She wasn't like the others—those rushing trainees too caught up in practice drills to see the corners of their world. No, this girl belonged to the corners. She was the corner. Like the flickering light bulbs overhead or the peeling paint on the third-floor landing. Always there. Always still. Always watching.
Minju had floated past her hundreds of times in those early days—back when she was still screaming silently at mirrors, back when the world passed through her like wind through empty halls. Most people didn't notice her. No one heard her.
Except maybe this girl.
The red cap was always pulled low, shadowing her face. Her hoodie bore a trainee badge, long faded, the number unreadable. She stood between the third and fourth floor like a forgotten checkpoint. Never moving. Never speaking.
Minju had once tried to approach—curious, desperate, aching to not be the only ghost trapped in that place. But the moment she stepped too close, the girl had turned, and with a flicker, vanished. No scream. No smoke. Just—gone.
Minju didn't try again.
She had other worries. She was trying not to unravel. To stay herself. To remember her own name.
And still... the girl remained. Quiet as dust. A fixed point in the building's breathless rhythm.
Sometimes Minju wondered—was that her future? Was that what happened if no one ever saw you?
There were moments—brief, flickering—when even Haru saw the red cap girl. Twice, to be exact. Once in the hallway mirror. Once by the staircase, when she flickered into view and out again before he could speak.
He never tried to talk to her.
Minju understood. You couldn't always reach the ones closest to the edge.
But she had been reached. Haru had seen her. Spoken to her. Let her exist again.
And it changed her.
Minju laughed more now. Glowed more. Drifted lighter. She no longer haunted the halls. She floated through them. She didn't just watch life from the edges—she followed it. She belonged to it again, even if no one else knew.
One afternoon, after another chaotic rehearsal where Haru tripped over his own sleeve and Riki tried to pass it off as "floorwork," Minju zipped down the stairwell to relive the moment in peace.
And froze.
The girl wasn't there.
The landing—the one place where the red cap figure always stood—was empty.
A flicker of unease pricked her chest.
She turned slowly—
The girl was at the top of the stairs.
Facing her.
For the first time, they made eye contact.
Minju hovered midair, uncertain.
The girl didn't vanish.
Instead, she lifted her hand slowly, fingers curling like a broken radio signal finding frequency for the first time in years.
Minju raised hers in return.
Their hands didn't meet—couldn't—but something passed between them. Not warmth. Not touch. But something that recognized the other.
The girl tilted her head. "You glow now."
Her voice was brittle. Like a door creaking open for the first time in a decade.
Minju's smile was quiet. "Someone saw me."
The red cap girl's shoulders hunched slightly. "Lucky."
A long silence filled the stairwell. Not heavy, not cold—just old.
Minju floated a little closer. "Were you… waiting for someone?"
The girl nodded. "My brother. He said he'd come see me dance. He promised."
Minju's heart cracked a little. "Did he?"
"He got sick. He never made it."
Her voice didn't waver. She wasn't crying. But something in her faded hoodie seemed to sag under the memory.
Minju swallowed. "Did anyone ever see you? After?"
The girl shook her head. "They forgot me. All of them. Even the staff. It's like I wasn't real."
Minju hesitated. "You are real."
The girl looked down at her feet. "Doesn't feel like it."
A pause.
Then Minju floated until she was eye-level.
"Maybe you just need someone to talk to."
The girl blinked at her like it was the strangest idea in the world.
Then, very slowly, she sat down on the stairs. She took off her cap. Her hair spilled down—matted, but soft, curling slightly at the ends. Her skin wasn't as gray anymore. Her outline was a little more solid. Like the act of being seen had started to pull her back into shape.
"What's it like?" she asked.
"Being seen?"
A nod.
Minju thought for a long moment. "It's like… like waking up. Like remembering how to breathe again."
The girl didn't speak. But her shoulders relaxed.
Minju tilted her head. "Wanna come heckle Haru with me?"
The girl blinked.
Minju grinned. "He screamed at a moth yesterday. It was amazing."
For the first time, the red cap girl smiled. It was shy. Crooked. But real.
"That was him? I thought I imagined that."
"Nope. That was 100% Haru. He dropped his mic and everything."
The girl giggled—a sound so faint it nearly didn't happen.
Minju offered her hand again. This time, the red cap girl reached back.
And even though their fingers passed through each other like mist, neither of them flinched.
"Come on," Minju said. "You don't have to haunt the stairs anymore."
The girl took one last look down the landing. Then she nodded.
And together, two ghosts slipped through the wall—
Not alone anymore.
