Natsuki is a shy, bookish girl. She hasn’t made any friends since starting high school. Even her brother ignores her. She spends her days alone. But one day, she overheard some classmates talking... Selfies... secret accounts... desire for validation... It all sounded VERY interesting to Natsuki. She was a bit nervous, but started a secret account of her own. A few selfies were all it took for her phone to start blowing up with notifications. The huge response made Natsuki take more risks... Then one day, someone asked her to meet up. She’d only ever felt desired by strangers online. It was time to do something about that. And so she resolved to meet this man for real...
