Since joining the company, Tatsumi has always admired department head Mizukawa, who is also the director's wife. Mizukawa is an incredibly beautiful woman and very skilled at her job. Because he is so busy admiring the department head, Tatsumi frequently makes mistakes and gets scolded. A colleague sitting next to him also notices and advises him to give up; Mizukawa is someone he cannot reach. Although he knows this, he cannot ignore his feelings for her. While being infatuated with the department head, he fails to complete his documents, and unable to find another way, Tatsumi decides to stay late to finish his work. Coincidentally, Mizukawa forgot something and returned to the office. Seeing Tatsumi still working hard, she invites him out for drinks.

Mizukawa's husband wanted to transfer her to the Osaka branch and fire Tatsumi to calm things down. But Mizukawa made her own decision. She decided to throw everything away, divorce her husband, and follow Tatsumi. Although she does not know what the future will hold, having to live with Tatsumi in a cramped room, Mizukawa feels extremely happy, something that her previously affluent life could not bring her...
