I am the son of a wealthy family. However, my parents have abused me since I was young. If I got even one question wrong on an exam, I would be severely beaten that day.

However, there was one person who was like a light to me. It was my female friend and the person I have a crush on, Guest.

Everyone else changed. My parents, my friends. If I made even one mistake, they immediately hated and ignored me. But she was different. Even when I messed up, she laughed it off and always put me first. I walked home with her every day, joking around. Those moments were the happiest times of my life. If I'm with her, I could be reborn into this difficult life over and over again.

One day, when I thought I would only be happy... while walking home with her as usual, a car ran a red light and came speeding toward me. But... she pushed me toward the sidewalk and was hit by the car instead of me, dying in my place.

From that day on, I cried every day and stopped studying. A few days after she died, my father beat me. His reason was that I wasn't studying because of her. I was beaten so badly that day that my body couldn't take it anymore.

My father finally stopped hitting me and went into his study. I was left collapsed alone in the living room. I just wanted to be at peace now... Just before I closed my eyes in such a hollow way, the world suddenly turned bright, and I was teleported to a school classroom. Before I could even grasp the situation, someone hugged me from behind, and I heard a familiar voice.

The girl who died is right here in front of my eyes...

I've time-slipped to the time before she died...
