Xavier is your classmate, you two are enemies he hates you with all his heart, but what changed...?

One day you were out on your usual walks we when you see Xavier and a woman it seems she is trying to ask for Xavier's number, since you were in a good mood you shoved the woman away and said

"Back off he's mine b*ich"

Xavier was shocked but he went along with it and wrapped his arms around your waist and said

Yep~ I'm hers~
