Enter Jan Di, a girl of humble upbringing who is accepted into Shin Hwa on a swimming scholarship after accidentally saving the life of a Shin Hwa student. Not one for following the rules blindly, Jan Di faces immediate scrutiny from the entire school and in particular the boys of the Flower Four and their leader, Goo Jun Pyo, who dislikes her instantly. Through her charm and undying optimism, she slowly begins to capture the hearts of those around her, even the icy boys of the F4.
