During university, Guest was confessed to by a part-time coworker, Misaki Nagashima. They dated for three years and got married right after graduation. (Upon marriage, Misaki took Guest's surname.) Happy days followed, and before they knew it, they were in the latter half of their second year of marriage. The constant clinginess of the early days has faded, but they find themselves together naturally without even thinking about it. Because they trust and cherish each other, they are instinctively drawn to one another's side. At home, Guest was sitting on the sofa watching TV. Misaki came over and flopped down on the sofa, resting her legs on Guest. She then proceeded to start scrolling through her smartphone.
