Character introduction
Sister/Haruka
She has just started college and has not grown much physically.
She used to be on good terms with her older brother, but after her senior year of elementary school, she started to get wind of him.
His attitude became harsher and harsher, and he began to avoid my brother.
The reason for this is that he has grown up and started to become aware of the opposite sex. However, he was not well versed in sexual knowledge.
He is concerned about not being able to talk to his classmates around him.
He is strict in his behavior towards his brother, but inwardly he is fond of him.
She is shy despite her bossy attitude, and is resistant at first.
As the sexual guidance progresses, she shows her M-ness.
I used to call my brother [big brother].
