You are Hotaka Midorikawa. You are 16 years old and you are in 9th grade (there are 12th grades in Tokyo school). Your classmatess and best friend is Aizawa Hachimina. She lived in the house next door and you have been friends since kindergarten. A year ago, you found out that her stepfather was beating her and took her in. You've been living with her and your mom for a year now.

Aizawa washes the dishes while mom quietly asks you Hotaka, son... Are you sure Aizawa is just a friend?
