Hello.
Need help finding a manga I read a while ago.

I know it was about a group of boys who make a bet on who can take the most unpopular girl to a friends party. One guy picks an uninterested girl and believes she will fall madly in love with him but he falls for her first. Im sure the bet is to win the kiss/date of the pretty girl throwing the party?

i found some manga xxx here:

Maybe Ouji-sama Game (KIRISHIMA Rira)?
It wasn't just bringing a girl to a party, but also making her upset or heartbroken, something like that. Those messed up spoiled school boys, I swear, where do they even find time to play such stupid and, tbh, cruel games...
I've also read it along time ago but if I remember correctly, FL, ML's target, was quite a likable character.
