Yoko and Futaba are in a pinch and need to find part-time jobs to earn money. Along the way, the three girls meet Shino Sonobe, Yoko's eccentric former maid.
An accident temporarily puts Yoko out of commission, so Futaba and Hayama help out at the patisserie. While Miss Sonobe is certainly grateful for the help, she won't stop until she's acquired one more part-time employee.
Yoko, Futaba, and Hayama learn more about each other as they continue to eat lunch together. They encounter a rival, a sibling, and cats. All the while,Yoko is deciding whether Hayama is kind-hearted or black-hearted.
Hayama goes to a cat cafe with her sister and sees Nishiyama there! Futaba has a free ticket for the petting zoo. Then, Futaba wants to start up a band.
It's Christmas and it also happens to be someone's birthday. Then, the end of the year approaches, and it's almost New Year's. How will Hayama, Futaba, and Yoko celebrate these holidays?
