In class 6-1, there are always full of... weird pupils. Henry, Chanyeol and Taemin are the kingkas. Nana, Hayoung and Bomi are the queenkas. The class clown, Kwanghee. Don't forget the geinuses, Xiumin and Hyuk. They have a big difference of personality. Xiumin is a cheerful boy while Hyuk is a person that would be handsome enough to join the kingkas but have a strange dark aura around him. What would happen if a new girl enters the class?
