Members from Earth Arcade gather again! But this time, they must run the Space Rice Cake Shop in Goheung, a center of K-Space and a branch of the head office on the Moon, because they failed the mission given by Torong in the past. To run the shop, Lee Eun Ji, Lee Young Ji, Mimi, and An Yu Jin go through lots of hardships, waking up at 5 a.m., making and selling never-before-seen rice cakes, and providing special services. Everything seems normal, as if all they have to do is manage a small shop in the countryside. However, once they mention a second branch, almost despite themselves, one really opens in Seoul. And a lot of tasks beyond making and selling rice cakes begin. What do they have to do while managing both shops? Will they successfully run both shops and satisfy the customers, despite the endless work?
