Choi Y/n and Jeon Jungkook are class fellows, studying at Seoul's National School. Y/n is madly in love with Jungkook ever since the day she saw him in grade 8, but being an obese girl Jungkook avoids her. Everything in Y/n's life was going fine until the day she proposed to Jungkook but to her luck, the thing that came to her was nothing....except insult and humiliation. She broke so badly that she left....leaving everything behind....returning as Kpop Idol...bringing a storm into Jungkook's life.
