Lost in the mountains during a trip to summer camp, eight-year-old Si-Joon fears he will never survive. When a strange girl wearing a pig mask appears before him, he follows her to a house deep in the woods, where he is told that he must marry the pig-faced girl to atone for the sins of their ancestors. Si-Joon is not too keen on getting married, but that wedding feast looks so delicious! It is only afterward that he realizes what he has done and... wakes up. Now in high school, Si-Joon Lee has been dreaming about the pig bride for as long as he can remember. But it is all just a dream, right?
