A Tropical Fish Yearns for Snow, Vol. 4

A sudden fever keeps Koyuki from participating at the Aquarium Club open house during the Nanahama High School culture festival. After a successful solo amberjack show, Konatsu stops by to wish Koyuki well and teasingly compares her to the salamander from a short story. Now Koyuki can’t stop thinking about how Konatsu once compared herself to the frog from that story. As school obligations keep them apart, Koyuki and Konatsu start to realize just how important they are to each other.
