Yoon Haejoon, is a brilliant thoracic surgeon who graduated from Korea University. She performed the surgery of a patient with the intention of saving people but that patient disappeared without paying hospital bill ! The hospital bill is alone 7 million won. She bowed her head in front of Lee Han, the beast, who seemed to not get a drop of blood even if he was stabbed. " I'll pay you back. I will repay you somehow." " In what way?" asked Seomun group's successor and chairman of Seomun First Hospital, Lee Han . His biggest regret is that he only has money . " How about 10 million won at a time?" " I'll give you this amount of money only if you meet with the director and pretend to be my lover , will you?''
