After his power-harassing boss damaged his spirit and health, Momose quit working and started a new sales job for an advertising agency. However, on the very first day of his new job, while making rounds to see clients with his new boss, Momose frets, "What should I do if my new boss also abuses his power?" and is unable to move due to a stomachache caused by his past traumas. Alone, Momose anxiously worries, "If I don't hurry and stand up…I might get kicked." But just what exactly does his new boss Shirosaki do…?!

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'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.

Inside a train station with high passenger foot traffic, Momose and Shirosaki look upon a giant advertisement. The release day of Momose's first ad, which he created for the aquarium, has finally come. On his way to the aquarium, Momose spots a man at a nearby café who looks like his previous boss, Kurono. Even when he enters the aquarium, he ends up remembering Kurono. While accompanying Momose, Shirosaki notices a suspicious man. The envelope that the man holds has the name of Momose's previous company written on it….

At Kinjo's suggestion, the four hold a Christmas party and bring presents. Momose continues his daily search for a new property as he decides where to move but is saddened that his fun life living together with Shirosaki will come to an end. After the party, and after much deliberation, Momose decides to move forward and contacts a real estate agent to assist with his move. And finally, the day of his move arrives...
