Haruko Omae returns to S&F, a large food company, after 13 years. He accomplishes any task with ease while helping his employees, Fukuoka and Chiba, who are being treated unfairly.

In an attempt to show off his abilities, Takeshi Shoji brings Haruko to a client's office to work as his secretary. But when he discovers her superhuman skills, he loses face and they engage in a furious dispute.

After participating in a domestic tuna project for the Fisheries Department, Takeshi is put in charge of a tuna cutting show. He requests Tsune-san, a renowned tuna butcher, to clear his schedule for a day.

Miyuki is taken aback by how low her starting salary is; Takeshi appoints Haruko as his secretary and begins business talks with a Russian company.

The HR department chooses to terminate contract employee Shigeru Ogasawara when the National Tax Bureau inspection begins; Kensuke plans to hold a sale for shio-musubi.

S&F hosts a Valentine's Day event in partnership with a well-known chocolate business. They hire a temporary employee scheduled to serve as the announcer, but she cancels at the last minute.
