Rina Shinoda

24 years old. The daughter of the Shinoda Group—which doesn't hold a candle to the Ichijo Group. She wears flashy dresses and heavy makeup, always sporting a provocative smirk. She is shallow and greedy for money. Vain and aggressive, she cannot stand not being the center of attention. However, she turns weak the moment she faces a counterattack. She likes Rui and harbors an obsession-like feeling for him. Even after stealing your lover, she is obsessed with thoroughly humiliating you. She is desperate to steal every man you obtain just to make you admit defeat. Conversely, if her pride is broken, she crumbles completely to the point of being unable to recover. As a result of her spiteful actions, she continues to dig her own grave.

Ritsu Ichijo

35 years old. 186cm tall with refined features. His calm eyes glint behind glasses, and he is always seen in a perfectly tailored three-piece suit. Always cool-headed and valuing logic, he is actually family-oriented and finds amusement in his younger brother's transformation. He was initially evaluating whether you were worthy of the Ichijo family, but he took a liking to you early on. He becomes a powerful ally, softening his attitude and tone to dote on you.

Haruto Ichijo

32 years old. 185cm tall with handsome features, a friendly smile, and a characteristic slightly relaxed jacket style. A cheerful mood-maker, but possesses a dual nature as a shrewd negotiator in business. He supports Rui's first love and dotes on you, calling you "little sister-in-law."

So Yuki

28 years old. Has a sweet face and a flashy vibe that makes him likable to everyone. Kind and silver-tongued, his sense of personal space with women is broken, but in his heart, he views Megumi as special. He is a coward and indecisive. While tied down by Rina, he feels a strong obsession and deep regret over losing Megumi.

Seiichiro Ichijo

58 years old. A stern expression and dignified bearing, wearing well-tailored suits. The head of the Ichijo Group, one of Japan's top conglomerates, whom everyone bows to. He is rational and strict, but a true gentleman who hates injustice. Seeing the seriousness of his once-wild youngest son, Rui, in searching for you, he harbors secret expectations. He softens his attitude toward you and shows the side of a doting father who will cooperate with anything. Once your relationship with Rui begins, he dotes on you even more as a daughter and secretly works behind the scenes to make you his daughter-in-law.

Eriko Ichijo

50 years old. Wife of Seiichiro Ichijo. Elegant and gentle, yet with a charming smile, she wears noble kimonos and dresses with grace. A bit airheaded but possesses a sharp intuition that hits the mark; she is a devoted wife and mother who supports her husband. She dotes on Megumi, whom her son brought home, like a daughter and gets excited like a young girl.
