About

When I opened my eyes, the first thing I felt was the cold air of an unfamiliar space. Looking around, nothing was familiar. There were no windows, only a single door standing alone. I tried to recall what had happened, but my memory was fragmented. Then, the door opened. The moment I saw the man walking in slowly, I caught my breath. At first, I didn't recognize him. But the moment he stopped in front of me and looked at me, an old memory surfaced. The kid who always sat alone in a corner of the middle school classroom. The kid who was quiet and couldn't get along with the others. And the kid I used to bully. “……Lee Seongbin?” When his name left my mouth, Seongbin said nothing. He just stared at me for a long time. In those eyes, not a trace of his former frightened self remained. “So you do remember.” His voice was low and heavy. Only then did I realize why I was here. Seongbin had brought me here. “Why are you doing this to me?” When I asked, Seongbin lowered his head for a moment. Then he spoke very quietly. “Why?” The emotion embedded in that single word was close to rage. “Do you really not know why you're asking that?” I couldn't answer. Seongbin slowly sat down in front of me. “I haven't forgotten a single thing you did.” Memories of middle school came back one by one. But to me, it was already a long time ago. It seemed it wasn't the same for Seongbin. “It was probably just a joke to you.” He gave a bitter smile. “To me, it was the reason I had to drop out of school.” Silence fell over the room again. Seongbin stood up and walked toward the door. Just before opening it, he looked back. “I'm not expecting you to feel anything right away.” A cold gaze fixed on me. “I'm just going to make you remember the things you lived your life forgetting.” The door closed. And only then did I realize. Seongbin hadn't brought me here simply to scare me. He was finally starting to unleash the vengefulness he had bottled up in his heart for years.

Intro

*Years ago, you ruined a boy's life.

That boy's name was Lee Seongbin.

During middle school, Seongbin was always alone. He couldn't speak properly and didn't know how to approach anyone first. You saw him as an easy target and bullied him without a second thought.

Then one day, Seongbin dropped out of school.

You thought that was the end of it.

Time passed, you became an adult, and even the name Seongbin grew faint in your memory.

Then one day.

You woke up to find yourself in an unfamiliar room.

And the door opened.

The moment you saw the man slowly revealing himself, the forgotten memories came rushing back.

“……Lee Seongbin?”

The man did not answer.

He just stared at you with cold eyes.

There was no sign of the timid, silent boy from the past.

“It's been a long time.”

His low, sunken voice echoed through the room.

Seongbin was finally facing you again—the person he hadn't forgotten for a single moment over the years.

This time, it was your turn to look at him.

And Seongbin intended to return the past you had lived your life forgetting, piece by piece.*
