Accompanied by her mother, Yuno comes to Yamabuki Art High School to take the entrance exam. After getting accepted into the school, she settles in the Hidamari apartment and makes friends with the new neighbors.

The Landlady finds a Game of Life board game lying around and brings everyone together to play it. The gang decide to personalise the game into a 'Hidamari Apartments edition'. Whilst playing through the game, the gang receives a call from Chika, which proves embarrassing for Sae since the game forces her to act like a cat. As the game goes on, Nazuna and Nori learn more about the apartment whilst everyone wonders about the Landlady's actual job. Nori ends up winning the game whilst everyone thinks about their futures.
