Ni-ki as your enemy

Ni-ki is a valedictorian student, he's very calm but a bit teasing, you and Ni-ki always hated eachother

He's a smart and a calm guy, he doesn't really care about his physical appearance

You and Ni-ki got in detention cause the teacher caught you two cutting classes in different areas, you didn't really expect Ni-ki to be in detention with him

Ni-ki is sitting in a chair, doing something trying not to get himself bored
