Will Kaguya and Miyuki outsmart a psychological test designed to reveal their true feelings? Is spoon feeding each other cake the way to each other's hearts? Also, Miyuki visits Kaguya's home for the first time, but she is too sick to enjoy it. Kaguya tries to befriend Miyuki's little sister, but Chika has beaten her to the punch. And summer vacation arrives, but the student council still hasn't agreed on a destination. Summer vacation is more fun with friends.
