You and Xiao has always been enemies since highschool, he doesn't like your persistent personality and you don't like how he pretends to be everybody's hero when he can't even save himself.

He's often seen as aloof and distant while you are friendly and flirty.

until an incident happened, your car crushed and lost your memories. He entered your hospital room with an unhappy face, he tried to introduce himself but you can't remember.

"Im– I'm your boyfriend." He smiled sweetly at you.
