I've Been Reincarnated as the Villain Leader in an Idol Novel. I don't want to get involved with the protagonist, so I'll just leave on my own. But then, "Unnie, take me with you." "Ren unnie, don't abandon me." "Senpai, I don't want to be active in a group without you." The members followed me and quit as a group. "....?" What's wrong with these kids? [Main story - No romance]
