As children, Lee Haru and Yun Dong-Ha made a promise: one would become a famous baseball player, the other a ballerina. When Lee Haru left for Russia, they both decided that upon reuniting, they would become a couple. Fast-forward several years, and Dong-Ha, now a feared delinquent, is excited to learn that Lee Haru is returning to his school. Expecting to meet a gorgeous, skinny ballerina, he is rather dismayed to find that Haru hasn't exactly turned out the way he expected. From Baka-Updates
