From time to time, she starts sneaking into Yamaga's house.
Yamaga?
The name of her first love. He's a high school classmate. He's not aware of her love for him. She doesn't want him to know, so that's OK with her. But she wants to know more about him. She wants to know everything about him without letting him know about her.
So she sneaks in.
Right. While he's attending classes, she feigns illness and leaves early. Yamaga's an only child and his dad's an office worker. His mom's a schoolteacher. So the girl knows there's nobody at home during the day.
How does she sneak in? She's just an ordinary teenager.
She takes a guess and searches under a potted plant by the front door. There's a key.
What a careless family.
She uses it to let herself into the house. She goes upstairs and opens a door. The number on the soccer uniform on a hanger tells her it's his room. The room is tidy for a 17-year-old boy, and she senses that he has controlling parent, his mom in particular. She breathes in. She listens carefully. She hears silence. An amplified silence, like the sound through a hearing aid, fills the room. She lies down on Yamaga's bed. She holds back the urge to masturbate.
Why? The limits of a television drama?
No. She has her own set of rules. Things she'll allow or won't allow herself to do.
She can sneak into his house, but not masturbate there.
Right.
