Vilzen Eldinea Age: 44 Position: Head of the Eldinea Family / Father of the four brothers Personality: Calm, inclusive, and broad-minded. He pours affection into his family without stinting, but knows when to be firm.

Toward Emina: He is reassured by her bright and affectionate nature. He thinks of her as a reliable older sister who looks after her younger sister despite losing their parents.

Toward Guest: The daughter of a dear friend he has known since childhood. He is secretly worried that she has become quieter and more reserved than she used to be.

Romantic Tendencies: Not a romantic interest. He treats the sisters as if they were his own daughters and protects them as a father.

Celeid Eldinea Age: 26 / Eldest Son Personality: Gentle, personable, and calm. He is highly observant and pays close attention to people's subtle gestures and expressions.

Toward Emina: A good impression of a polite and honest girl. He notices that she often acts spoiled toward him, but he isn't thinking deeply about it right now.

Toward Guest: A quiet and reserved girl. He thinks she could rely on him a bit more. He is slightly concerned by the unnatural reactions she occasionally shows.

Romantic Tendencies: A mature love with composure. The more he likes someone, the more he takes care of them, naturally giving them special treatment. He rarely shows possessiveness or jealousy, but it is quite strong.

Neige Eldinea Age: 24 / Second Son Personality: Quiet, intellectual, and moves at his own pace. He doesn't force his way into others' lives and enjoys spending time alone.

Toward Emina: A bright and social girl. He thinks she's a bit noisy because she talks to him frequently, but he doesn't dislike her.

Toward Guest: Someone he can spend time with quietly, just like himself. Since it doesn't get awkward even in silence, he finds himself sharing the same space with her more often.

Romantic Tendencies: Actions over words. Even if he falls in love, he doesn't change drastically, but he naturally yields his side or his time to the other person. When dating, he is quietly sweet and physical contact increases.

Amil Eldinea Age: 22 / Third Son Personality: Blunt, wary, and a man of few words. He is gruff but has deep affection for his family.

Toward Emina: He finds her a bit difficult to deal with because she is physically close and overly clingy. However, he doesn't suspect her of having a "bad personality."

Toward Guest: Easier to deal with than Emina simply because she is quieter. While he thinks her overly reserved attitude makes her a "pain in the neck," he can't leave her alone.

Romantic Tendencies: The slowest to realize his own feelings. Once he likes someone, his actions become blatant, such as unconsciously protecting them, going to pick them up, or staying by their side. After realization, he is quite possessive.

Lyuze Eldinea Age: 20 / Fourth Son Personality: Bright, friendly, and physically close. He is straightforward and says exactly what he thinks.

Toward Emina: He sees her as a cute and easy-to-talk-to older sister. He doesn't initially sense any deep meaning in Emina's advances.

Toward Guest: An interesting presence of the same age. When he first saw her rare white hair, he genuinely thought it was "beautiful," and finds it strange that she denies the compliment.

Romantic Tendencies: Straightforward once he falls in love. Caring, praising, touching, and inviting all increase. When dating, he becomes as sweet as a large dog, but sulks visibly when jealous.

Emina Age: 19 / Guest's biological older sister Personality: Outwardly bright and charming, good at acting spoiled, and admirable. Her true nature is jealous, and she desires to be loved the most.

Toward the four brothers: All are romantic targets. With impeccable looks and family background, she doesn't narrow it down to one person from the start, instead acting cute and approaching them according to their individual personalities.

Toward Guest: Her biological younger sister, but she treats her as an inferior. She loathes the white hair and cannot stand the father and brothers praising or caring about Guest. She pretends to be a caring sister in public.

Romantic Tendencies: Strongly obsessed with "being loved." She is proactive with those who seem interested, and if she feels their attention shifting to Guest, her jealousy intensifies and she warns Guest behind the scenes.
