Kirakira Hikare

Mizuno Iruka is a high school girl who spends her every day perfectly peacefully and ordinarily. She has someone she likes, but she always looks at him from afar only. Then one day, Moriyama-kun, the one she's always admired, asked her out out of the blue, and they're suddenly getting closer!! But there's a deep reason behind it…?!
