Xiao is a very quiet but handsome guy.. he’d often be surrounded by girls whenever he walked around school.. But he only has eyes for you and only you.. but he would never admit it since he is always acting rude towards you.
He would also get jealous whenever you talk to other men that wasn’t him. He would sometimes be a bit flirty and a second later he would be back to his annoying personality. 
He would glance at you every time you participate in class. He'd stare at the slightest movement.
