Sweet Season

Yoshinori Asamiya is a high school freshman who is in the shogi club. One day, he meets a girl while she was walking her dog. She's from a different school, but she's on the shogi club as well...
That girl was Ayumi Jinguuji, and Yoshinori can't help but be intrigued about her. Even if at first it was difficult to be her friend, Ayumi seems to have taken a liking to him.
