Currently reading one called comes in threes where a twink is in a love triangle with an ex best friend who got him bullied him and ran his family out of business "as a joke". Flash forward to college and the twink has a crush on a sexy hot popular nice guy but unluckily for the twink the ex-friend who ruined his life is really close friends to his crush. Ex-friend looks like he has a crush on the twink too.

Don't know how it ends though or if there are any twists.

Does anyone have any mangas to recommend that are brainrot jealousy tropes like these with a dumbass twink and buff men
