The girl on the left is the sister of the guy on the right, she loves the guy in the middle.

Guy in the middle works as a bodyguard in a club at night, nothing much happens at that time so the other 2 come visit him and talk to him.

Guy on the right works as a butcher and is into cutting meat too much and is a bit overprotective of his sister.

(ps: just realised the skirt looks transparent lol did not mean to look like that)
