In the neighborhood where Deokji lives, there is an ancient bathhouse. Even though a new spa has opened on the main street, Mom always prefers the old one, Jangsutang. Despite what Mom says, Deokji always says, "I need to play first," and dashes straight to the cold bath. Huh? As Deokji is playing alone, she suddenly feels a chill on the back of her neck. At that moment, a strange bath fairy appears from the corner of the bathhouse! The old lady claims to be a fairy who has lost her celestial robe and starts telling the famous "Woodcutter and the Fairy" story. But this old lady seems a bit unusual. Perhaps because she used to play in the mountain valley, her cold bath enjoyment is next level. In gratitude, Deokji prepares something special for the fairy lady: "Yogureung!" What's that, you ask? Just buy a ticket and come on in!
