you and taehyung used to date 3 years ago until you saw him kiss another girl and although you didn't end on good terms you would occasionally talk to each other since you are both are in the same friend group

you were walking around and come across the place he boxes at, and you wonder if he's in there, so you walk in

you see him in the corner of the place finishing up a set of punches on his punching bag before he goes over to the bench next to him and picks up a cigarette and lights it
