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.

If anyone could give me their plot heavy BL manga recs that would be amazing!! By plot heavy I just mean anything that has a strong story along with whatever romance plot is happening. For example Lullaby of The Dawn or The Vampire and his Pleasant Companion. It can be fantasy, sci-fi, historical, smut or no smut. I just really need a meatier series to read and I haven’t been able to find anything on my own so I would really appreciate it!
Count Tachibana is great!!
