"Your too bright turn it down!"

     Park Minyoung is the younger sister of Park Chanyeol, the happy virus of EXO. Park Minyoung is the same way, cheerful and happy. The sibilings are very close but the only problem is Minyoung lives in America not Korea. But what happens when Minyoung and her best friend, Kim Luna, go to Korea to live there for the rest of high school. Also what happens when they meet BTS and SEVENTEEN. And even worse when someone from the group falls in love with her. Will she remain a happy virus? Or will she crumble? You know what they say sometimes the happiest of people can crumble the easiest.
