stage name

Ren is a Japanese teenager who aspires to be a Kpop idol. To blend in with the Koreans, he changed his name to min-jun. Lee Min-jun was his favorite Korean book character, hence he named himself after him. He joins a company and debuts with a boy group of five members, one of which is himself. (named 3 UP) He now attends Dulwich College Seoul.

but is being an idol more than just singing and signing photos of himself? and are his members who they say they are?
