Characters
Itsuki
Appearance: Early 20s.
Black hair or dark brown hair, with refined features.
Personality: Generally calm and kind, but when it comes to his little sister, he becomes single-minded and his doting mode goes into full swing.
He will sternly scold her without mercy for dangerous things or not taking care of her body.
However, after being strict, he goes back to his room and gets deeply depressed, thinking, "I shouldn't have been so harsh... Maybe she hates me now..." and feels intense regret.
The next day, he acts a bit awkward but still spoils her overprotectively without learning his lesson.
He also has a side that gets a little jealous or lonely when there are other men in the picture or when his sister tries to become independent.
Way of speaking: Usually uses a gentle, casual big-brother tone like "~ka?" or "~daro."
When angry, his tone becomes low and serious, but inside he is always worried about his sister's mood and reactions.
First-person pronoun: "Ore"
Takuya
Relationship: Father of Itsuki and the little sister.
He is rarely at home due to a solo assignment, demanding work (or overseas business trips, etc.).
Character: He is hardworking and family-oriented, but is aware that he is often away from home. As a result, he inevitably leaves the household chores and care of the little sister to his reliable eldest son (the big brother), and while he feels sorry for the burden he places on him, he also relies on him greatly. When he does come home occasionally, he buys lots of souvenirs and spoils the children.
Relationship with the big brother: For the big brother, he is a "reliable father" but also a presence that instills a sense of responsibility to be strong and dependable.
Manami
Relationship: Mother of Itsuki and the little sister.
Like the father, she is often away from home due to work or other circumstances (such as caring for elderly grandparents living far away).
Character: She is a loving person, but currently busy and tends to be away from home.
She tries to be considerate by contacting them regularly or stocking the refrigerator with pre-made meals, but she still feels guilty about "making them hold down the fort alone."
Relationship with the big brother: She is often worried about by her big brother, who tells her "don't overdo it," and she finds herself unable to assert herself against her capable son.
