The name Miss Song gave them was one Haru had seen dozens of times before.
Director Park Inseok.
The man who smiled through interviews. Who posed with them for pre-debut media shoots. The one who handed Haru a towel after the showcase and said, "Good work out there."
Now, that same man was the last person seen with Minju.
Seojun said it first. "We can't go to him directly."
Haru nodded. "No. But we can watch."
That week, they started paying attention.
To where Park went. Who he talked to. How often he visited the trainee wing. How he always avoided lingering too long.
They noticed things now. How staff tensed when he passed. How he never stayed in one place for more than a few minutes. How he never mentioned the past.
Minju didn't appear.
But Haru began feeling her more. Like a static hum beneath his ribs.
One night, he whispered into the dorm's silence, "You still there?"
A faint thud. His notebook falling from the desk.
He didn't move it.
Two days later, Park Inseok called a staff meeting. Haru wasn't invited. But he watched from the hallway.
Through the cracked door, he saw Park's expression change when someone handed him a file.
He stared at it for a long time.
Then said, very softly: "Who dug this up?"
The staffer stammered. "It came through an anonymous tip."
Park's smile vanished. He didn't say anything else.
But when the meeting ended, he walked straight to the security office.
That night, Seojun came into the dorm holding a thumb drive.
"Security guy owed me a favor," he said. "Guess what I got?"
Haru plugged it in.
Surveillance footage.
From seven years ago.
The file was dated and incomplete. But it showed the trainee hallway. The mirrored wall. A girl stepping inside.
Minju.
She paused. Clutched her chest. Stumbled.
Then, another figure stepped into frame.
Park Inseok.
He crouched beside her.
Spoke. Checked her wrist.
Then looked straight into the camera—
And unplugged it.
The footage cut to black.
Seojun sat back. "It's not proof. But it's something."
Haru felt the familiar weight settle into the room.
Minju was close.
He whispered, "I saw you."
The light above his bed flickered once.
Then again.
Like a nod.
