At her school things are totally difenert from any other school. There are five boys who controls it. Each one of them has his own fan club. Every girl has to belong to one of those fanclubs and Eun Mi belongs to Yoochun's fan club. Yoochun is the love of her life, her dream guy! But because of a bet that the boys made (who will have the most official members in a year) all 5 fan clubs have the same number of official members. It was a tie! Now that Eun Hye came to school, the boys will try to make her member of their fan club to win the bet. Eun Mi's life will change completely because of Eun Hye's decision not to register in a fanclub at all.
