Papa tells the story of three couples: The first couple could be defined as "True Love" After living a beautiful romance on the campus Hyun Jun (Bae Yong Joon) and Se Young (Lee Young Ae) marry, but as the emergence of everyday difficulties the love between them begins to be shaken and finally when Young misunderstands the Hyun Jun's relationship with Hye Min ends up filing for divorce. The second couple could be defined as: "comic love" A love as comfortable and natural as the friendship between two people. Yong Gong is a schoolmate of Se Young besides being a doctor of a natural medicine clinic or as it is known oriental medicine. He is a widowed father and one day he goes to the pharmacy and meets Hye Won and is attracted to But it is at this point that we see the difficulties in harmonizing Eastern medicine (which is based on natural measures) and Western medicine (which is based on medicines). And the third couple that we could define as: "The animated and naive love" It is a love typical of the 90's generation where we see a playboy by nature IN Pyo (Jung Chan) who was accustomed to many adventures with girls. One day he meets his niece's teacher Sae Byeol's kindergarten.
