A dirty, messy vacant lot with some trash piled up. There is a large tree there. Seeing the tree, Seobin remembers the trees in her country house yard, happily hugs the tree, and tells it her story. At that moment, Jaru, a goblin, appears. Jaru is 753 years old and is a goblin born from a transformed broom. The two become friends and spend enjoyable time together. Jaru gives Seobin a goblin hat that allows her to fly, and Seobin goes to the countryside with Jaru to meet her friend Sangmi.
