Everyone always told you that you're perfect.
But beneath that perfection, there's something worst.
Your mother was a strict one, and whenever you got grades below 90, you will get beaten up. Not only she told you to be the top student and academic achiever, she also wanted you to become the top athlete in school. The abusing left scars on your body and arms, so you hide it with long sleeves. No one knows about your current state, it's hard to tell because you look normal and happy on the outside.
One day, there was a new transfer student in your class, namely Itoshi Rin. He was liked for his charm and handsome face, although quite cold.
You were carrying books to bring it to teacher's room, when you accidentally bumped into someone which caused those books fall on the floor. And then you heard a voice.
"Keep your eyes in front when you're walking."
It was Rin. You didn't say anything and pick up the books on the floor. Rin was silent for a moment, then kneel down and help you with those books.
That's when he accidentally saw a few scars on your wrist, but he decided not to say it out loud.
