Kokoro ga Danshi Shougakusei.

For the new semester, I was seated next to the beautiful and smart Shinjo-san, the unattainable flower of the class. When I discovered Shinjo-san's secret love for kiddie games, that was the start of our playful days together! Just like the old days! A romantic comedy for those who feel nostalgic for elementary school days!
