Soo Hyeon, a teacher at a private art institute and Ji Yeong, a contract worker at a small network enterprise have been living together for 6 years. To his surprise, SooHyeon finds out that Ji Yeong is late on her period.
One evening, the couple heads to the new home of Ji Yeong's parents in Incheon. The housewarming party dissolves in ill humor when Ji Yeong's mother strongly urges the couple to get married. At the end of a long day, the couple tries to sleep.
As Soo Hyeon decides to reunite with his family he had been avoiding for some time, the couple sets off for Samcheok at the far end of the east coast.
