it was about a girl who goes to a bar with her friends (i think) and is full of boys and for the boys to talk with you you have to buy expensive drinks, they would act like your boyfriend, and this girl would spend a lot of money in this guy who doesn't really love her.

Do you have a picture or something 

Do you remember if it was Japanese, Chinese, Korean, Thai... because of the language or the environment?  any more details would help

Boy for Rent (2019) maybe

is not boy for rent :( i dont have any picture i just remember that there where girls in a club and they would then also sell themselves so they can afford to pay for drinks in that club to receive boys attention

Sounds like a classic story of someone falling into the trap of thinking money can buy affection. It’s sad, really. She’s probably looking for genuine connection but ends up wasting time and money on someone who’s only in it for the drinks. People can be pretty manipulative in those settings.
