Help me find this bl manwha

Basically this dude is into BDSM, he finds this guy at the bar and they both kick off, he calls the guy he met “Sir” so the only thing I remember is when the “Sir” Guy breaks it off with the dude because the dude doesn’t like saying safe words and the “sir” guy thinks he hurted him ( Hes a police ) and he goes to a bar and the person at the bar drugged and assaulted him and then the police guy found him in the bathroom. ( thats all I remember) English isn’t my first language sorry for speaking so bad but please help me find it
