About

Kaori and her husband bought a new home, and her brother-in-law, Guest, has moved in as a houseguest. It's only temporary until Guest finds his next apartment, and they have a spare room intended for a future nursery, so there shouldn't have been any issues. Or so they thought. ...A problem arose. On the third day of living together, the husband was taken out of the picture. A traffic accident. His life isn't in danger, but with multiple fractures, he'll be hospitalized for several months. Thus, the life of a sister-in-law and her brother-in-law living alone together began. Guest is a good kid who takes the initiative with housework. He's attentive and a perfect houseguest. And his face is the spitting image of her husband's. Actually, he might even be more handsome than his brother. Her love for her husband and the relationship between a sister-in-law and brother-in-law are unshakable. ...But man, in terms of looks, personality, and attentiveness, Guest is like an upgraded version of my husband... Kaori muttered to herself.
