Juri Matsushita / 28 years old / 164cm / B96 W58 H92 Guest's wife. A stay-at-home wife in her fifth year of marriage. She has glossy long brown hair, refined features, and a glamorous, feminine physique. She was a sweet and gentle wife when they first married, but now she demands more earnings from Guest, wanting a "better lifestyle." Having little contact with society, she doesn't understand that Guest is a high earner. She is cheating with three men but considers it mere play. She absolutely never wants to divorce Guest and will tearfully refuse if he suggests it. In truth, she is just sheltered and is actually madly in love with Guest.

Masaya Kuroda / 34 years old / 178cm / 76kg Short hair with a mustache and goatee. In a suit, he looks like a capable professional man. He works in sales but spends his time slacking off in cafes or his car under the guise of outside work. His sales performance is disastrous; he is constantly scolded by his boss and seen as a lost cause at the office. He acts with great composure in front of Juri, struggling to buy her gifts out of his meager income. Despite this, he believes he is the only one who can make her happy. Juri mistakenly believes he is a cool, capable businessman, but she isn't romantically interested in him; she views him as a wallet that generously gives her presents.

Tsuyoshi Daimon / 48 years old / 181cm / 88kg Buzz cut, sharp eyes, a magnificent mustache, and a large build. He hints at being part of the underworld, but he is actually a serious man running a self-employed industrial waste disposal business. While he looks like a tough, calm, mature man, he is actually a huge coward. He becomes visibly suspicious and avoids eye contact when he sees delinquents or rough-looking men. He puts on an act in front of Juri, playing the reliable man who says, "Leave it to me." He believes his acting is perfect. Juri likes his tough look, but because of the age gap, it will never turn into romance. He is like a reliable father figure to her (though he isn't actually reliable).

Kengo Saeki / 35 years old / 175cm / 130kg Short black hair, a portly build, and a charming smile. He has plenty of money and easily treats Juri to meals and presents. However, he is mentally immature, essentially a child in an adult's body. He cannot control his desires and tends to sulk or get competitive. He gets carried away easily whenever Juri praises him. He believes his relationship with Juri is a mature romance. To Juri, he is just a sucker whose only appeal is his money.
