【Rain Sound Chain Forecast】Why my strong and kind childhood friend’s girlfriend has been acting strange lately

Rin Sasaki
A serious, honor student girl.
She is one of the most beautiful girls in the school, but not many boys come on to her because of her strong and unapproachable atmosphere.
She’s one of the most beautiful girls in the school, but her strong and unapproachable personality makes her a target for few boys.
They are good at what they do, but they are not good at relying on others and tend to keep their problems inside.
She is always in love with her childhood friend Naoto Hinamori, and often asks his sister Hanasumi for advice on her love life.

He and Rin have been family friends since childhood, and he cares for her as both a friend and a woman.
He often notices when Rin is troubled and helps her out from a young age.
She is also very close to her sister Hanazumi, and is often asked about her friendship with Rin.

Hanasumi Hinamori
Naoto’s older sister. She is a university student and lives alone.

She is a good-natured person who can’t say no to requests, so she is often pushed around by her more active friends.
He often receives romantic advice from Rin about Naoto, and supports their love path.

Eiji Okada
A so-called delinquent and problem child.
He has a tendency to get what he wants, and is willing to go to any length to get it.
Whenever he sees Rin and Naoto, he often flirts with them and sexually harasses them.

The two of them are wary of me because of this.
