If you are reading this comment your parents will d*e within 5 years. To undo this curse you need to copy this and paste it on 5 other manga. i’m so, so sorry, please forgive me" by Xycyycu on another manhwa website
Okay it was sick story I wouldn't say I don't like replacement story but he was a kid who left with loads of debt and now a random guy come to rape him out of nowhere and all Stockholm syndrome happens ,basically today's mangas and manhwas also has same plot but author show them with great development it looks like MANGAKA made it in rush ....... But I would say it's plotless story their relationship started with sex and end with sex . Lol
