Daikichi helps look after Kouki while Yukari recovers from her cold. Later, Rin practises for a skipping rope contest, with Daikichi joining in so he can lose some weight. After the contest, Daikichi takes Rin to see his parents, where one of Rin's wobbly teeth comes out. Daikichi also talks with his sister, reminding himself of the words of wisdom given to him by Yukari and his adult friends. On the way home, Daikichi reflects on the past year he has spent with Rin.
