Koharu finds that her boyfriend was a married man, who was cheating on his wife with her, and was the third guy to do so in a row. Desolate, Koharu decides to leave Tokyo and move back home, rejecting a future of love and marriage for a simpler life. However, once she arrives, she discovers that the café that her parents ran is closed and they are heavily in debt. A man, Ryunosuke Date, who was following Koharu, offers her to pay their debt, but Koharu has to marry him. Koharu learns that her hometown has legalized polygamous marriages to counter declining birth rates and becomes Ryunosuke's third wife.

Koharu is short-tempered and often lashes out at slight annoyances. She was at first against polygamy and sexual intimacy due to past trauma caused by her exes, but she gradually resolves her issues as she comes to terms with her feelings for Ryunosuke, begins to get along with his other wives and becomes a bonding pillar in the Date family. • Ryunosuke Date • Yu Inaba • Ryunosuke Date is the 25-year-old husband of Yuzu, Madoka and Koharu.

She is the mother of Ryunosuke's first child, Rinnosuke. • Madoka Date • Nana Asakawa • Madoka Date (née Saijō) is the 21-year-old second wife of Ryunosuke. She often wears a kimono at home.
