Ever since Taeyang's first love, Ga Eun, dumped him in the worst way possible, Taeyang has sworn off the company of girls. He acts coldly and rudely toward them. When Taeyang moves to a new highschool, he finds that his ex girlfriend, Ga Eun, goes there as well. To make matters worse, Taeyang discovers that the reason Ga Eun broke up with him was because she was with another boy named Jin ho, who she is still currently dating. Hurt, Taeyang wanders around the school until he bumps (literally) into the sweet and innocent Jung hee. He then comes up with a plan: get with Jung hee to try to make Ga Eun jealous and win her back. However, things don't go quite as he planned, but one thing is for sure. Taeyang's second love story will not end like his first.
