a manga like this where Seme is like the youngest son who enters the mafia or business world and the uke who was seme's older brother or father's fucktoy helps Seme take revenge or take control over everything something like.... A lot of people warn the Seme about Uke like he's just a slut and not to take him seriously but it turns out the Seme met the Uke at a young age and developed a crush so at the end he wanted uke to be his.. I think the seme had blonde hair and uke just had black or brown. The uke is obviously older but not old old
It might be a Japanese manga or Korean manhwa, but I don't think it was in color. I can't completely remember this detail either.
