I can’t remember the name of this one manga (help)

There was this trap looking guy. (I think he was an actor). Which he took a role as a girl when he was young. And the child working with him fell for him thinking he was a girl. But when he found out he was a guy he had an existential crisis but still tried to be with him. The main character had a big brother who had a brother complex. The big brother was having a relationship with his manager. Anyone who knows it if they can reply, they’ll make me very happy.
