Isezaki, a second year from Kamiyama Boy's High, has had his heart captured by a girl he saw in the window of the neighbouring girls' school. A school route madonna!! After two months, it's time for her to graduate...?! It's a 17-year-old's summer starting from spring, chockful of idiocy and friendship enough to make you cry.

Also included is an extra story called Fuyu Hodoki in volume one.
