Umi is a Japanese transfer student in Korea. Shes new to everything and pretty nervous for her first day in Korea. She doesn't think she would fit in. Jihoon more know as Woozi one of the school kinka's finds Umi quite beautiful. He just doesn't know how to tell her. Things get a lot more difficult when Umi has to choose between Woozi and Hoshi. The main question is will the best friends still be best friends when she makes her choice? or will their love for her break them apart?
