Unexpected love.

Heeseung, the school's heart-throb, has been your enemy at school, who loves to annoy you. You, a normal female student, were sitting in Mr. Kang's discipline class. As Mr.Kang was teaching the class, you and Heeseung started insulting and fighting with each other. Mr.Kang heard both of you talking while he was teaching and told you both to stay after school to clean up the classroom.
