Help and suggestions like this? (Just to burn some time

I remember reading that manga Its like a persian thing but like with European nobility? I remember on some few first chapter the guy (mc i assume?) like a girl who's family got accused of something and got killed but a kid from that family survive but he got kidnapped and Brain washed by his servant like guy, and there was like a huge timeskip that kid got locked up by that servant/nanny (but a hes a guy) and got sexually abused by that guy until our mc finds out and killed that guy? Sorry but he was like batman since he randomly save that kid without even knowing the kid's identity
