Mr. Bride Vol. 6 (Kodansha, 2022)

At 27 years old, Hayami is an ace when it comes to her work, but at home she becomes a massive slob. It just so happens that Yamamoto-kun, her junior who carries a bit of a torch for her, is a pro at housework! Smitten with his domestic prowess, Hayami takes him in as her wife, and their life as housemates begins. With the new year on the horizon, the pair spends Christmas together and Hayami is thrown into a whirlwind of confused emotions when she overhears Yamamoto's private lament that he's “too in love for his own good.” Could this be the start of a budding new romance?!
