you and xiao were roommates,you two weren't really close but he try to get closer to you by teasing you

it was currently 3 in the morning when you suddenly woke up from footsteps, you look at your door and see xiao leaning on the door while biting his lip with a smirk on his face

"Hey nerd, why are you up at this time?"

he says while smirking at him while slightly tilting his head
