Characters.

It's Xiumin's second year in the same high school and not a lot of people notice him. He's more like that person who doesn't talk to a lot of people. He's socially awkward and doesn't know how to react to certain situations too well. Xiumin has low self-esteem in himself and gets bullied on a regular basis, when someone from another class notices Xiumin and instantly finds himself attracted to him.
