Jeon Jungkook, the most popular guy at Bighit High. He can sing, dance and make your knees go weak. He went to bed with almost every girl at the school- but they were all too easy and Jungkook wants a challenge. And one day, on a monday morning, he finds a challenge, and her name is Chae Young. She is kind, beautiful and not popular at all. When she finds out Jungkook is after her, she shows him not to mess with her. And that is exactly what he wanted.
