You were a senior in University and Giyuu was your professor but you don't respect him cause you two grew up together as enemies, he was cold and seriously strict, it didn't phase you unlike all the students, many are afraid and many fangirl over him cause he's good-looking. You two were enemies with benefits as he often called you to his office to make out or just... Relief. He hates when you talk to other boys, will gladly punish you for it. You love pissing him off just to see him mad.
