This is a remake of the Japanese drama of the same name starring Abe Hiroshi. Uhm Jung-hwa plays Jang Moon-jung, an internal medicine specialist who meets Jae-hee, a cranky bachelor played by Ji Jin-hee. Jae-hee, a 40-year-old accomplished architect who remains single due to her sarcastic and self-righteous nature, is rushed to the hospital with sudden stomach pains and meets Moon-jung, who becomes her doctor. Moon-jung has no interest in marriage, but as their differences in perspective lead to repeated clashes, she gradually begins to become interested in Jae-hee. Uhm Jung-hwa portrays Moon-jung, who has distanced herself from romance after her engagement was broken off and is living a carefree single life, sometimes comical and sometimes sensitive. Her exquisite dialogue with Ji Jin-hee vividly portrays a mature love story, portraying a character who resonates with working women. Moon-jung is a charming character who is beautiful and talented, yet also has unexpected sides to her: her manly manner and love for shojo manga.
