Chan Sook and Taeyang attended the same high school where everyday Chan Sook would drool over him, hoping for him to notice her. But since Chan Sook wasn't great in her studies or in anything at all, Taeyang never took notice. But Chan Sook never lost hope even after high school and in college. Although they did not attend the same college she still dreamed about Teayang. During college Chan Sook made new friends(Kangin and Eun Ae). Kangin and Eun Ae were her two absolute best friends.
