MBC's latest kdrama "My name is Kim Sam Soon" the story about a fat 30 year old single pastry chef, who has just been dumped by her boyfriend. She is convinced that her shelf life for getting hitch is expiring, and as her window tightens so does her nerves. She is blunt, many a time foul mouth, but totally genuine and cute. 
Kim Sam Soon (SS) is a 29 years old, fat, pastry chef, who has just lost her job and her boyfriend on Christmas Eve. She has all the insecurities of a woman grazing 30. With yet another failed relationship, SS scrambles desperately to rebuild her career and her love life.
SS manages to find a job at "Bon Appetite" restaurant when she gets acquainted with the owner of the restaurant, Hyun Jin Heon (JH).
Due to a moment of convenience, both SS and JH ended up signing a dating contract, where SS will receive KRW 50 million won (which she needed to redeem her family house) and in turn she will pretend to be JH's girlfriend to fend off his mother's endless efforts to get him match made and married.
When JH's ex-girlfriend (Yoo Hee Jin) returns to seek reconciliation; SS realizes that she has fallen for JH, and their contractual relationship gets complicated. The main actress Kim Sung Ah put on 7 kg to play this role and she is one comic actress whom I think is so at ease as Kim Sam Soon without being Over-The-Top with her acting!
