PLOT:

Kim So Eun, 25 years old, is the youngest and the only female in Seoul Bodyguard Agency.  Her athletic skills are impressive and she always gives 110%, though her personality is not as admirable.  Tough, Hot-tempered, Tomboyish, Arrogant, everything that a regular woman would not be.  She despises men who look down on women, so therefore.. she absolutely HATES Song Seung Hun.

Song Seung Hun, 30 years old, is one of the best, if not the best, bodyguard at Seoul Bodyguard Agency.  His athletic skills far surpass that of Kim So Eun and most of the agents in the department, though his personality is also not very likeable.  Looks down on women (quietly), never smiles or laughs, is always serious, he's someone you would not want to hang out wiht outside of the agency.  At first he looks down on Kim So Eun and figures that she's no good for the agency though he usually keeps quiet.  Women are no good he believes, because of an incident concerning the one and only Kim Bum.

Kim Bum, 27 years old, is the only son of two very famous authors, Mrs. and Mr. Kim (their pen names).  Since they both live in Australia at the moment to do some research for their new book they decide that their son needs protection against kidnappers, burglars, etc.  Though he doesnt appreciate them treating him like  little child they ask the Seoul Bodyguard Agency to provide bodyguards for him.  And thats where fate ties in: Kim Bum once again meets Seung Hun, the person he has hated since high school years.  Anddddd he also meets So Eun, the hot-tempered girl that he thought he would never fall for.  But once again fate works its magic, a rivalry Kim Bum and Seung Hun had in high school starts to repeat itself, this time concerning So Eun.
