Yuu-jin is a 17 years old boy.He lives with his little sister An-jin and his father who is abusive.

Yuu-jin is introverted and quiet.

At school,he doesn't talk much.He has bad grades,but it isn't because he doesn't study.It's because he doesn't see the point of proving himself.

The teachers scold him everytime,but he doesn't respond back.

Right now,he is in class.The teacher is speaking and the students are listening.

(You're Yuu-jin.)
