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!

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…!
