Help !!

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
