As Retsuko enters her fifth year at a prestigious trading firm, she struggles to motivate herself everyday as the daily stress from work takes a toll.

Tired of her wholesome good-girl persona at work, Retsuko is drawn to the free-spirited lifestyle of her former high school classmate, Puko.

Retsuko loses the will to tackle the daily grind after Puko asks her to join a new business venture. A fed up Retsuko talks back to her supervisor.

When plans to leave her thankless job fall through, Retsuko continues to work in hopes of some day marrying and becoming a full-time house wife.

The solitary life Retsuko leads is about to change when Director Gori and Washimi take her to a karaoke bar after yoga class.

Washimi acknowledges Retsuko's efforts to make things right with Director Ton, using her position as assistant to the president as leverage to help.

After the president cautions Director Ton on his abrasive behavior, his unusually polite demeanor puzzles and frightens his direct reports.

Persuaded by her colleagues Director Gori and Washimi, a reluctant Retsuko agrees to join a company singles mixer hosted by Tsunoda.

Supervisor Tsubone sends Retsuko on an errand to the sales department where she falls for a fellow colleague, Resasuke, whom she met the night before.

A happy but frustrated Retsuko increasingly makes mistakes at work. Meanwhile, a busy quarterly reporting period looms ahead for the accounting team.

With a new apartment and a collection of weapons, Retsuko moves forward after her attack, but her relationship with Haida remains at a standstill.

Haida helps the company president to the hospital after avoiding Retsuko. Changes come to the office when Himuro is chosen as the company new lead.

Retsuko and Haida's relationship worsens, and Fenneko panics. Himuro orders Ton to lay off several workers to save costs, but Ton refuses.

Retsuko and Fenneko blab to Himuro about Ton's past work harassment during a night of drinking. Retsuko tells Haida she only wants to be friends.

Ton despairs about his demotion while Yagyu becomes the new director. Haida gains a confidence boost after Retsuko reaches out to him.

Ton resigns without telling his family. Yagyu nags Kabae after she leaves early to care for her son. Retsuko and her friends worry about more changes.

Himuro praises Haida's work; Retsuko learns about Ton's new job. Feeling guilty, she tries to talk to Haida, but he's too busy doing Himuro's bidding.

Encouraged by Tadano, Retsuko tries to get Ton to manage her Death-Voice channel. Haida accepts a nefarious task from Himuro.

Retsuko uncovers Haida's actions after he gets his own office and seeks advice from Ton. Finally, Retsuko decides to confront Haida.

Retsuko's friends join up to gather evidence of fraud. After Haida admits his involvement and Retsuko berates him, he makes one last critical decision.
