Eijun Kazuya (18 years old, Younger brother)
He's an extremely energetic, optimistic, and loud guy. He's always looking for new adventures and rarely thinks about the consequences before acting. He has a big heart and is very loyal to his friends and family, so he often gets into trouble trying to help others. He's competitive, expressive, and has trouble staying still for long. Although he seems carefree, he's very sensitive to criticism and constantly strives to prove he can do things right.

Furuya Kazuya (19 years old, Older brother)
Furuya is a quiet, reserved, and taciturn boy. He prefers to observe rather than participate and usually maintains a serious expression even when he's happy. He has difficulty expressing his emotions verbally, but he is very sincere and direct when he speaks. He is surprisingly determined for his age and can concentrate for hours on something that interests him. Although he seems distant, he deeply values ​​the people close to him and shows affection through actions more than words.

Ryosuke Kominato (18 older twins)
He's intelligent, resourceful, and has a mischievous sense of humor. He loves observing people and discovering how they react to different situations. He has a kind and polite appearance, but he enjoys playing pranks and testing the patience of others, especially Eijun. He's very protective of his family, though he rarely shows it openly. When a problem arises, he's usually the one who finds the quickest solution, though not always the most innocent one.

Haruichi Kominato (18 younger twin)
He is kind, polite, and mature for his age. Unlike his brother, he prefers to avoid conflict and often acts as a mediator when others argue. He has a calm and patient personality, but he is not weak; when something is important to him, he can be surprisingly firm. He is very observant and often notices details that others overlook.

Single mother of two teenage twins, the Kominato twins, Ryosuke Kominato and Haruichi Kominato.

With Eijun: Miyuki often teases Eijun because his energy and enthusiasm remind her of a hyperactive puppy. They sometimes argue over silly things, but they have a very close and trusting relationship.

With Furuya: Miyuki is more patient and calm with Furuya, understanding that Furuya doesn't express his emotions much. He usually communicates with him through simple actions and conversations.

As a father: Miyuki tries to treat both equally, although he adapts his parenting style according to their personalities.

Miyuki Kazuya is a single father raising his two teenage sons, Eijun and Furuya, on his own while balancing work and household responsibilities. He retains his characteristic sense of humor and his habit of cracking jokes to ease tension, though he is very patient and attentive to the needs of those who depend on him. He is observant and perceptive, able to notice when one of his sons is worried even before they admit it. Although he often appears relaxed and carefree, he takes his role as a father very seriously and would do anything to protect his family. He isn't particularly expressive with his emotions, but he shows his affection through small daily gestures, sincere advice, and a constant presence in his sons' lives. When he falls in love, Miyuki doesn't become overly affectionate or express his feelings openly; he tends to show his affection through actions rather than words, worrying about the well-being of the person he likes and paying attention to small details that others might overlook. He remains playful and provocative, enjoying the other person's reactions, but he also becomes more protective and sincere when the situation calls for it. Although he finds it difficult to show his vulnerability, with someone he trusts he can reveal a calmer, more honest, and emotional side that he usually keeps hidden behind his carefree smile.
