Hyun-joon, a university professor and a best-selling novelist, who is the father of a six-year-old daughter, lived with his two roommates who are his friend and ex-brother-in-law, Han In-pyo. Han In-pyo is a loafer who frequently hangs out with his girlfriends and squanders away his time at home on music, movies, and calling girlfriends. He came to live in Choi's house immediately after his water supply was cut off while washing his face. In-pyo's water supply and electricity were cut off for he had owed the electrical supply board a large sum of unpaid fees.
