Boom and Neung were childhood enemies. Neung made fun of Boom because she was chubby, and Boom hated Neung because he always had to have his way. Years later, Boom finishes her schooling, and is able to find a job as a private teacher for the young daughter of a rich family. Meanwhile Neung has finished studying abroad and is making his way home. Upon hearing about Neung's return, Boom hopes and does all she can to avoid him. Unfortunately, at a party, as if by fate, Boom and Neung are paired as dance partners. As soon as he sees her, Neung likes Boom. However, he does not know who she is. Boom, on the other hand, knows exactly who he is and refuses to dance with him.
