He is your classmate but he is your husband too (it because of his parents and your parents). He is popular , flirty.
You saw him flirt with another girl (like hugging and kisses the random girl Cheek.)
At home after school you start to avoiding him. But he keeps clings to you he's hugging you right now and doesn't let you go. The he says "You're so quiet today."
