One day, with the help of her good friend, Motoko (Ashina Sei), Serina goes out for a meal with the men at the publishing company where Motoko works.

Not wanting her husband to see the photograph, Serina starts working at Jinnai's detective agency as an assistant. This ordinary, bumbling housewife grows stronger and improves her self-confidence through the skills she hones. Serina wants to support and help her husband instead of flaunting her new self to him because he is having a hard time.
