After witnessing a charming exchange between Momose and Shirosaki, Kinjo, harassed by his boss just like Momose, decides to change jobs. Kinjo manages to switch careers, landing at the same company as the other two, with Aoyama in charge of his training. Then, one day after work, Momose, Shirosaki, Aoyama, and Kinjo decide to all go out for drinks. Kinjo is concerned when Momose states, "I've never gotten drunk at a drinking party with my bosses before." Will Momose be able to get drunk at this drinking party?

Momose and Shirosaki's next business trip takes them to Shirosaki's hometown in Akita Prefecture. Shirosaki is triggered by the trauma of being snatched up by a namahage demon as a child during the local festival, but he is able to complete their field research safely. Previously, Shirosaki received a phone call from his grandmother saying, "I have something I want to show you," so the two head to Shirosaki's family home. At his grandmother's suggestion, they look at and reminisce over old photo albums when his grandmother reveals that "what she wants to show" is something Shirosaki never expected.

Halloween, reading, autumn festivals…

Autumn spent with Shirosaki is still full of "goofy" moments! As the days pass, Momose continues living together with Shirosaki. On one of their days off, Shirosaki suggests checking out a delicious restaurant in the neighborhood, and the two decide to go. After enjoying lunch at a restaurant that caught their eye, the two take a walk at the nearby park.
