Beloved Noona

Hyejun is the leader of a K-pop group called Beaster, that had become really popular after their debut. But in the past when he was only a child actor, he suffered a lot of abuses from his father and manager, and was later saved by one of his ex step-moms, Mila.
Now, after six years without knowing where she was, he finally meets her again, as his new manager.
