The one your not supposed to like

First of all who is this

Well he's my best friends ex guy bsf who kinda had a fling with her but never dated.Right so off the bat this is messy but it gets worse.I know just about everything about what happened with them like all the details. Well i always Said he was such an asshole because i never really knew him.Well now the more i talk to him the more i start to catching feelings but there not normal like I wanna date him and change him and make him not so broken and cold ,but at the same time I want him to absolutely ✨rail✨ me and leave it at just hookup idk if it's just the hormones talking rn anyways that's all about who I'll tell you more about what our conversations are like later.so basically if anything happens I will tell you about it they probably will be very short
