http://www.mangago.zone/read-manga/love_bite_lamyo/ read that it really pisses EVERYONE off it's a little different to what you said but the uke does cheat on the side seme (ukes bf) pretty much throughout the whole manwha with the actual fucker of a seme
Please recommend yaoi mangas or manhwas where the uke walks in on the seme cheating on him....Like full on cheating and maybe remorseful or maybe not...Don't care if they do or do not end up together...I just feel like i need to read something pissing off and sad.
