All I remember is that the seme has a brother maybe a twin but also maybe he had a different hair color. I keep reading semantic error thinking it’s that guy but it was a yaoi. I think the brother was a lawyer and the semes grandfather was rich or something. I’m not sure if the brother had his own spin off or not. I do think there was a slight misunderstanding troupe. Or perhaps this is one of my delusions.
