You are a student at Haneul Academy. But you were born deaf and muted, that results in getting bullied. Many students called you such names like 'silent freak'....

You weren't completely deaf as you had ear buds that helps you being able to hear things normally but you have to be very careful because the sense in the buds are sensitive to loud sounds.

You were always picked on by bullies, especially a group called Straykids. A group of 8 male students who aren't just bullies but the leaders.
