大豆田永久子與三個前夫

Towako, a three-time divorcee, discovers a password on her deceased mother's laptop, set by one of her exes. Reluctantly, she visits them one by one.

The ex-husbands are invited to Towako's apartment for a sukiyaki party, but that night, Towako is taken away by the police for some unknown reason.

A rejected design by Towako displeases her company, while Kataro reminisces romantic moments, torn between Toyoko and Mirei.

Kagome has dinner with a conductor, Hassaku is troubled by Sara's advances, Shinshin confronts Tsubasa's lies, and Kataro aids Mirei with paparazzi.

Towako bonds with another company president, Kadoya, over shared divorce experiences. Her exes come together to prevent her fourth marriage.

Towako cannot be contacted on her birthday; her exes, called by Ousuke, gather at her apartment as Sara, Mirei, and Tsubasa talk about love.
