It's been a long time so I kinda forgotten, but the first couple, the uke have a brother that hate him. The second couple is about the brother. (That or the brother is from another spinoff I forgot lmao), but tbh I don't think the brother problem really a big issue in the story, at least what I remember.

Extremely specific request, but is there any manga/hwas where the protagonist has family issues like the plot is centered around the mc’s family, preferably brother issues. Like their brother just utterly hated them. Mommy/daddy issues is also alright. Any genre is fine but preferably romance, straight or not, it doesn’t matter
