CHIN's

The group – Momose, Shirosaki, Aoyama, and Kinjo – end up going to a last-minute mixer. Momose becomes depressed when bad memories resurface of a mixer he attended with his previous boss. But as the current mixer kicks off, Momose and the others get absorbed in Aoyama's story. When Kinjo follows Aoyama, who had left his seat during the mixer, and asks if there's anyone he is interested in, Aoyama becomes somewhat evasive. It seems there is a reason that Aoyama has become the life of the party…!

The one-hundred-year-old Fujiya inn stands in the quiet region of Kyoto. Mikoto is standing in front of the Kibune river at the back of the building when she is called back to work. But two minutes later, she finds herself back at the river again. The whole inn seems to be stuck in a time loop!

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.

While enjoying his time living at Shirosaki's home, Momose finally decides to tell Shirosaki about his former boss, Kurono, properly. From when he first started at the company, how he thought he had to live up to Kurono's expectations, to the power harassment that worsened day by day, Momose tries his best to tell it all. Later, Momose returns to his apartment for a change of clothes. Although it is dark and he can barely see, Momose catches a glimpse of a shadowy figure outside his apartment from the window!

Momose and Shirosaki stay at a hot spring inn when it is decided that they will go on a business trip. At the same time, Aoyama and Kinjo go on a single-day business trip to Kumatte Land. After arriving at the inn, Shirosaki realizes something important when he sees Momose naturally enjoying his time. On the other hand, Aoyama and Kinjo are suddenly hit with heavy rain on their way home after walking around and finishing up at Kumatte Land. Thanks to assistance from the public relations staff, the two stay at the hotel. But Kinjo catches a cold….

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?

One day, Momose and Shirosaki come upon an abandoned kitten in a cardboard box along the side of the road. At first, the kitten was scared of Shirosaki and intimidated him. But because of Shirosaki's gentle words and actions, the kitten gets attached and decides to go live with him. Since taking in and raising the kitten, Shirosaki struggles to decide on a name when he suddenly remembers the time he mistook a tanuki for an abandoned cat during his childhood. Shirosaki recalls the name he and his grandmother gave the tanuki back on that sad day they returned it to the mountains. What name will Shirosaki give to the kitten…?!
