My Beloved Is My Husband's Boss?!.

In Jimpachi Kodera's household, young samurai Keishiro Kanie arrives, captivating Jimpachi's wife, Shoko, despite his initially arrogant demeanor. Keishiro introduces himself while Shoko is cleaning, and she recalls her husband mentioning a visitor, reluctantly preparing a meal for him. Frustrated by Jimpachi's silence about Keishiro, Shoko confronts him, but he remains tight-lipped, further irritating her. As Keishiro addresses Shoko as "Okami" (landlady) and speaks informally with Jimpachi, his innocent and unpretentious nature gradually wins Shoko over. Despite initial irritation, Shoko is drawn to Keishiro's kindness and dependability as they spend more time together.
