3 person kpop group engaging in stupid life choices, girl accidentally kills a guy, they all commit suicide at end after being chased by cops.
It was a kpop song, and there were three people in the group that did it - two guys and a girl.
The girl is working at a salon, giving a guy a haircut, and the guy tries to assault her. In the struggle, she accidentally kills him. She runs outside, and gets picked up in a car by a guy who got into a fight, and was presumably a drug dealer due to the large amounts of cash later seen in his truck.
The pick up another guy, who is seen trying to kill himself numerous times, when he steps into the street in front of their car.
They go to a club (?) and run from the police, when they get caught they jump off a bridge (?) together.
I believe my friend mentioned that one of the guys in it is also in another kpogp group.
