Abuse / torture porn if you don't have any taste.
MC gets traumatized by his mafia dad so he runs away to rich bitch ML for protection.
ML kills the pedo who was preying on MC and goes to jail. MC has to become a prostitute anyway because he wants to stay in that hell hole just in case ML returns. Cute stuff
ML ruins MC's life and murders his entire bloodline for the vine and only stops when he starts falling in love with him. MC is completely fucked up beyond repair but ML gets injured one single time so all is good.
MC saves ML from something but a random rat bastard lies that HE saved him. ML's only hobby is torturing and abusing MC but he makes one sad face and gives some cheap flowers so all is forgiven.
Rec: Read the start, skip the abuse, jump to ML regretting and close the manga. Whatever ending you can imagine is 100% better than the original.
ML is so afraid of homophobia he rapes a man.
MC is a demon slayer but he gets possessed by a demon who liked raping MC.
ML used to bully MC in high school but he quickly fell in love and became his stalker. MC discovers this 2 years later and gets his revenge trough bullying ML back during sex.
MC almost got bullied to suicide in high school so what does he do when he meets his ex bully again? he forfeits all his mortal possessions to him before being thrown away. At this point, he deserves to get swindled out of all his money, absolute fucking idiot. ''I want to have revenge from ML! I better give him all my money, let him use me and beg him to return when he leaves again''
ML hates his father for abandoning him and his mother but he decides to take revenge from MC instead because he's a coward and MC was an easier target. No, he never takes revenge from his father, why do you ask? Every possible bad thing happens to MC while both ML and his father get away completely free. ML pretends to be sad so all is forgiven.
