Please help me found a bl manwha name

There is this one manwha I am trying to find as I remember Reading in bato but then bato was closed so here i am searching it so it goes a ml is some sort of mafia or business man while the bottom was poor working somewhere bar or something like that and everyone treat him like shit. But a old woman was sweet with him so ml somehow went the bar and kill the guys there but ml was desparate for life so he was forced to work under ml as a servant cleaning the places and all . One day ml was drunk and he SA bottom but later he realised that he did something very wrong to bottom then he beg forgiveness and was turned into Green flag but later he had a misunderstanding caused by rival made him thought bottom is spy so ml isolated the mc and assaulted him even drug him to the point mc lose his sanity.

It would be a big help
