"I don't want to be your shy oppa... I want to be your manly oppa. But, I'm just... I'm just too shy". Park Jimin, a shy introvert who likes an outgoing and innocent girl and the sister of his best friend. As the shy boy he is, he can't seem to confess or show his feelings towards her. And at the thought of her brother that's overprotective. A/U: Hi~ I'm just a new author. So please forgive my sypnosis!!👐👐
