It’s time for Rin to start elementary school, which she attends with Kouki. To commemorate this, Rin and Daikichi plant a loquat tree outside their house after Daikichi tells her about he and his sister getting trees when they were born. That makes them wonder if Souichi planted a tree for Rin. Daikichi asks Masako and sure enough, he did. When Daikichi finds it, it’s a fragrant olive tree, just as his tree is.
So Rin starts elementary school, but we don’t really see any interactions at the school, at least yet. However, we get to see more Kouki and his friendship with Rin. And of course he acts like a typical boy and Rin has the typical female frustrations about it.
This episode kind had more to do with the idea of Rin growing up. She and Daikichi talked about the planting of trees and growing up with the tree and so forth. However, Rin seemed to get depressed over the fact that she didn’t know whether she had a tree from birth, which upset Daikichi as well, because he hated bringing up the topic and then seeing Rin get down because of it. And this, of course, led to another merry meeting between Daikichi and Masako.
Otherwise, there really wasn’t much going on. I expect we’ll see Rin’s and Kouki’s friendship grow (and we may end up seeing them get into some trouble eventually, thanks to Kouki), and hopefully we’ll see some of her interactions at school as well.
