Mr. Bride Vol. 1 (Kodansha, 2021)

Hayami is the it-woman at her job-she's cool, confident, and admired by all. But her has-it-all exterior belies a dark secret...her house is a mess, and she's no good at taking care of herself! Enter Yamamoto-kun-her colleague who thinks the world of her, and who refuses to let her slobbish behavior slide. Soon he's over at her house often enough that she asks him to move in with her! Where will this roundabout relationship take them?!
