I'm still trying to restore all the manhwa I lost so some should help me with this. There's this guy that's blond or so with green eyes I think he's name is yeesu or heesu idk. He's obsessed with a detective that grew up with a lawyer or another detective idk but the mother of the childhood friend is who killed the detectives mother. I don't really remember it but the heesu guy chained him in a house in a forest so that he couldn't escape or so

You guys who knows that bl manhwa that there were two couples and the seme of the first couple cheated with the uke of the other. Their partners found out when the caught them having sex with each other and the seme of the other couple beat the other seme up. Then fast forward to ten years the uke's company met up with the seme that was cheated on and they're doing business together and now the owner of the architecture company is setting up the uke that was cheated on with the seme that was cheated on. I can't remember the manhwa
