Childhood friends Ryouta Satou and Chika Koizumi are now fifth graders in class 5-2, alongside Yuuki Asano, Kazumi Aihara, Natsumi Hirakawa, Megumi Hidaka, Kouji Imai and Tsubasa Kawai. The single OVA moves through the seasons. In summer the kids are supposed to pull weeds around the school pool in the heat, but watching bugs turns out to be far more interesting. In autumn a maple leaf reminds Megumi of Ryouta's spiky hair, which causes some confusion. In winter the boys lose a snowball fight to girls they assumed were weak, with Natsumi leading the rout. In spring the kids hurry home from the playground to catch a new anime on TV. The episode is a comedy with romance and ecchi elements, and it was bundled with the limited edition of a manga volume. The staff and cast are the same as in the Kyou no Go no Ni TV anime.
