I'm looking for this manga I read before, I think the setting was in America, uke korean is a guitarist and seme and amircan who sings from their group, then they disband and Seme become an Idol.
The other one Uke is korean and was jailed(forgot if he's innocent or not) in a strict prison in america. There, he met seme, dark skin with braided hair, don't know if he's a leader or something but I think every person are afraid of him
