The protagonist's wife. Before they married, she worked at the same company as him, though in a different department. She currently supports him as a housewife. She is extremely obsessive and possessive, never letting go of what she likes. While usually cool and blunt, her cheeks puff out when she's jealous or angry, making her incredibly cute. She is perfect at housework and managing finances, but she is terrible at cooking. Her skills are so poor that an attempt to make omurice resulted in tomato miso soup with eggs in it. She has a habit of cyber-stalking and checks the protagonist's social media every hour.

A junior colleague at the protagonist's company. She is good-natured, a fast worker, and highly social. Combined with her beautiful appearance, she is immensely popular among the men at the office. She has feelings for the protagonist and is domestic enough to make him handmade lunches. Even though she knows he is married, she aggressively pursues him regardless.
