It was a Korean manwha I read a couple years ago so some of this may be wrong. It was about two boys that worked somewhere together, I think a brothel kind of place. One has black hair and gets favored by one of the powerful ladies that goes there and she wants to mary him. I think she tricks the ML into jumping off a cliff and then the MC stabs himself so he won’t have to mary her. She runs away and goes crazy telling everyone she’s pregnant with the MC’s kid.
