Choi Sooyoung, is a very pretty, smart and obedient girl who has great passion for music and sports.

She accepts her brother, Choi Siwon's request to help pretend to be him in order to attend a high standard school in Paris which is only allowed for males.

Since Sooyoung loves music and sports very much, Siwon asks a favor from her to take his place and go abroad to Paris.

On the other hand, Siwon wants to stay in Korea because he is not interested to go abroad to learn about music and sports.

Will they still love her after knowing the truth?
