It was hard for Kim Uram. A really hard time for him to accept the fact that he is now single. The whole school knew him as the best playboy in the school. He never been single even for a day. But now it's already 2 weeks he haven't  have a girlfriend. He blame everything on Junka. He dumped on her because of her annoying attitudes. Because of her obsess to blood type.

Usually girls dumped on him because he cheated on them but this time, it was different. He dumped on her and it felt like his pride was scratch. All of his friends laughed at him. He was regretting for bragging before this. For him, all girls are loser because dumped him although they already know that he is the biggest playboy ever but Junka was different from other girls. Junka sticked with him although she saw it with her eyes that Uram kissed other girl at the alley. He don't know why but he felt regret for dumping Junka. She's different from other girls. Although her obsession is kinda annoying, but he slowly learned how to appreciate love when he was with Junka.

He has these weird feelings when he was with Junka. Different feelings when he was with other girls. Whe he was with Junka, he could feel how does love life really is. He started to feel that his life is like an empty can without Junka. He knew that actually he still likes Junka. But for him now, it's too late. Junka changed her heart from Uram to another guy, Oh Juntaek. But he knows, the way he flirt girls will forever make other girls, including Junka, to fall in love with him.

So will Uram succeed to steal Junka's heart back?
