That bl manhwa where mc is in love with his obliviuos friend who also likes him and he tries to seduce his best friend thanks to crazy 2nd ml who "helps" him seducing him but just manipulates mc into having sex with him. That bitch is crazy he slept around and everybody knows he's a sex crazy addict who wants to have a 3some with both of them. The oblivious friend notices it and thinks they're in a relationship and tries to save mc. Mc sleeps with crazy 2nd ML and theres a scene where mc hides under the bed and crazy ml searches for him (it was a very creepy but funny scene) and they're both naked lol. Plss

Does anyone know any story similar to "Love begins in world of if"
where there's the protagonist who travels to a parallel world line where the guy who hated him in og worldline is nice to him in parallel world line?
