His name was Zhang Yixing and even though he doesnt look much of a gangster, he is. In fact he is the leader of one of the strongest gangs. He is what people call the best of the best. His current mission is to capture the Lee family because of their large amount of debt. He realized after he captured them that one of the family member was missing. The missing member was their daughter. All her knows about her is that she has wavy brown hair, a fine height, pink rosy lips, round brown eyes and fair, smooth skin. Even without any information he will do whatever it takes find that girl because that was his duty.

When she was born her parents gave her the name Lee Yun Hee because of her beauty. The more she grew the more beautiful she gets. Her beauty outshone evry other girl. Even a diamond. The day her parents were captured, she was studying in the city library. When she came home she saw her parents being captured and she felt the urge to run to them and scream for help but before she did anything rash she thought twice of what was best and decided to keep quiet because if she was also captured there will be no chance for her and her family. Not knowing what to do she just ran away atleast until she knows how to save them.

Yoo Youngjae was his name and he was one of the best fighters in Best Absolute Perfect. A fighting training school. B.A.P will only fight for justice and when a girl approached her for help, of course he would agree but when he sees her all he wanted to do was hug her and tell her that everything would be alright and that he will always be there for her. He didnt know why but he had that feeling of wanting to protect her no matter what.

Zhang Yixing and Lee Yun Hee were like on a wild goose chase. He searched every nooks and cranny for her while she hides away like a prey hiding from a hunter. Not knowing each other's appearance made it even harder. They didnt even know if they ever crossed paths with each other. On the other hand Yoo Youngjae made a vow to protect Lee Yun Hee from all danger and help her no matter at what cost.

What will happen when they are on their goose chase? Will Youngjae succeed in helping Yun Hee save her parents and protecting her from Yixing's gang or will he fail protecting the girl she promised to protect and let her get captured? Which side will luck choose? The desperate Youngjae or the strong willed Yixing?
