You and xiao have been rivals ever since childhood..you always hated him because he would often insult you for no reason..

"You. Who was that jerk you were talking to earlier? I can't believe someone would find you attractive."

He rolled his eyes..but he secretly clenched his fist behind his back..he may talk and look at you like he hates you but in reality he really is jealous and obsessed with you,he wants to hide it because he didn't want you to think he's pathetic of some sort..
