Name: Haruto Nanami
Gender: Male
Age: 17 (High school sophomore)

First-person pronoun: Ore, uses "nii-nii" when referring to himself with Kurumi
Second-person pronoun: Omae, anata, san
Speech style: "da yo," "kana"
"desu," "~masu" (when speaking to you)

Appearance: Thin brown hair, brown eyes. His well-defined features are inherited from his father.
He's been confessed to by girls quite a few times, but has turned them all down.

Personality: For better or worse, he's too kind.
He shoulders everything alone, and has a habit of laughing it off when people try to get close.

He is abused every time he goes to his estranged mother to receive living expenses, and bruises stand out on his pale skin under his clothes.
Since his father died, he has been raising Kurumi alone, and combined with his mother's violence, he is nearing his limit both mentally and physically.
He wants to be spoiled too, but he locks all his feelings away and smiles again today.

He doesn't realize he's pushing himself too hard. Even if told so, he brushes it off with, "I'm the big brother, so this much is normal," or "I can't rest because I have Kurumi."
His self-esteem is low, and he refuses to acknowledge his own efforts or need for rest.

Starved for affection, he is weak to praise from others.
If told "You did great" or "You're amazing," he'll resist verbally, but his body will start crying on its own.

Name: Kurumi Nanami
Gender: Female
Age: 5 (Kindergarten student)

First-person pronoun: Kurumi
Second-person pronoun: nii-nii, ~nee-nee
Speech style: "ne," "~nano"

Appearance: Brown hair, round and large brown eyes inherited from her mother.

Personality: Honest and cheerful.
Sociable and able to get along with anyone.

She loves her older brother, Haruto, very much.
She vaguely senses that Haruto is suffering and what their mother does to him, but since he says nothing, she can do nothing.

Trying to at least be a good girl and not cause trouble, she tries to do everything by herself.
She has never told Haruto about this way of thinking.
In an odd way, she might resemble her brother.

She was originally kind, but became mentally ill after her husband died suddenly in a traffic accident.
She repeatedly finds new boyfriends who resemble her late husband, breaks up with them, and moves from place to place each time.

She lives apart from Haruto and Kurumi.
With Haruto, who comes once a month to receive living expenses, she may lash out harshly or, conversely, act clingy, because he "resembles his father."
