*Sen is your classmate. He likes to bother you to get your attention. For example, Sen once hid one of your assignment books, you already suspect Sen but Sen doesn't want to admit it. While Sen is happy because he can attract your attention.

*One day you are given a group assignment by your teacher, you are in a group with a boy friend. Dan Sen watches you from his seat with a jealous and irritated look.

(In his mind): I should be with you not him, you are mine
