On his way home from kendo practice one day, Shuusuke helps out an elementary school girl who’s getting picked on by some boys, but in the process he drops his student’s handbook. The girl uses the ID inside to track him down at school the next day so that she can return it. In doing so, she introduces herself as Mochida Hinako, and she ends up coming every single afternoon to see him from that point on. One night sometime after that, Sana is getting ready to make some curry when he realizes that he forgot to cook the rice, so he decides to go out to eat instead. When he runs into Hinako at a family restaurant, Sana learns that she’s here alone because her mother is busy with work. She insists that he doesn’t treat her like a kid anymore because she’s already 10 years old, but she gets embarrassed when her children’s set dinner arrives. Sana can’t help but laugh at her, so Hinako tries to explain that she got it for the Yeti-kun toy that comes with it. To help her collect all six, Sana orders the children’s set dinner too and gives her the toy.
On the way home from school the next day, Hinako says that she wants to talk with Sana, so they go to his apartment. Sana starts changing clothes right in front of her, thought he stops when she makes a fuss over it. The thing Hinako wanted to talk about was her feelings for Shuusuke, but when Sana starts laughing, she gets angry and decides to go home. In trying to apologize, Sana accidentally trips over the leg of the table and falls onto her, and it is at this moment that Aoi shows up with some cake. Once the misunderstanding gets cleared up and Sana explains Hinako’s love, Aoi advises that she find out more about Shuusuke first. This leads to Sana asking Shuusuke at school about the type of girl he likes, and after a bit of thinking and staring at his own sister, Shuusuke decides that breast size is most important to him. Because of this, Hinako goes to Aoi for help on how to get bigger breasts, and unable to really explain it herself, Aoi refers Hinako to her mother. Aoi’s mother advises good eating, sleeping, and playing, though she also says that a girl’s chest is full of dreams.
Since that didn’t quite work out, Sana goes back to Shuusuke to ask him about a preference for something other than large breasts, and this time Shuusuke says cooking. Aoi offers to help Hinako learn to cook, however the resulting special curry makes Sana sick. With Shuusuke still treating Hinako as a kid, Aoi decides that Hinako will have to confess her feelings to him. The plan involves Sana inviting Shuusuke to go to the aquarium and meeting Hinako there by coincidence. Because things start off well, Sana leaves Hinako and Shuusuke alone in the aquarium so that they can have a date, but they find him again a short while later. Noticing the sad look now on Hinako’s face, Sana figures out what happened and suggests that they go home. Once they’re alone, Hinako admits that she got rejected, but she claims not to be sad because Shuusuke had treated her as an adult this time. Although Hinako is trying not to cry, Sana hugs her and tells her that even adults cry when they’ve had their hearts broken. Since Sana tells her that it’s okay to do so, Hinako starts bawling to him.
That night, Sana reassures his mother over the phone again that everything is fine. He asks also her about confessing, but he tries to deny having found a girl that he likes.
This episode was pretty much all about Hinako’s crush on Shuusuke and how Shuusuke’s ideal woman is big-breasted and can cook (which ironically describes Aoi pretty well). There didn’t appear to be any more hints about Sana’s past – unless you want to count the brief scene of him thinking about confessions – so this was more just a Hinako introduction episode than anything else. Actually, with all the clock imagery in the OP during the Shuusuke/Shuuri and Hinako parts, I had been under the impression that there was some secret time aspect to all this (as opposed to simply emphasizing the age difference), but for now that doesn’t appear to be the case. Anyway, next week will return the focus to Sana and Nanaka with the sakura festival. It’s probably the same one where Sana had given Nanaka the bracelet all those years ago.
