Summary
Mihari recalls a time she went shopping with Kaede in middle school.

Plot
During a day when Mihari and Kaede were first year middle school students, Kaede is shown waiting outside a clothing store. She thinks to herself how Mihari invited her out shopping, and how she believes that Mihari will be so fashionable as she is a super genius after all.

Mihari eventually calls out to Kaede and apologizes for keeping her waiting. Kaede is shocked at Mihari's outfit and asks her what she's wearing, much to Mihari's surprise. Mihari is wearing track pants underneath a skirt. Mihari says that she's wearing them because it's cold today, and she runs track. She claims that everyone wears them at school. Kaede claims that she can't wear that stuff out here and tells Mihari to take off the track pants now, pulling them down herself much to Mihari's shock. Mihari can't believe that Kaede just embarrassed her like that with all these people around, while Kaede remarks that she's the one who should be embarrassed here.

Kaede asks Mihari how she can be this clueless about fashion, to which Mihari points out that that is why she asked Kaede to help her.

Later, the two leave the store with some new clothes. Mihari calls Kaede a lifesaver, saying that she never would've known where to start. Kaede realizes that even Mihari has things that she's no good at. Kaede remarks that Mihari ended up getting a super cute, girly outfit today and asks her if that's the kind of thing she likes. Mihari says that it is what her older brother likes, explaining that they are going on a trip together soon and that she wanted something for it. Kaede understands and remarks that she's sure that he'll like it. Mihari says that she hopes so.

Back at home, Mihari tries on her new cute outfit and looks at herself in the mirror. She wonders if it is cute, but also thinks that looking at it in the comfort of her own home, it looks a little over the top. She wonders if she can wear it in public, and decides that she'd die of embarrassment. She decides that she can't wear it on the trip and banishes it to the bottom of her closet.

Several years later, in the present, Mahiro is sitting at her computer playing a game. Mihari comes in and says that she's got Mahiro's clothes for the day; the same outfit from all those years ago. Mahiro notices that the clothes are cuter than usual, and Mihari points out how Mahiro likes cute clothes, while apologizing for it being a hand-me-down. Mahiro is surprised that Mihari used to wear this, saying that she doesn't know how to feel about that. She begins to sniff it, which causes Mihari to tell her not to.

Mihari notes how the clothes that she couldn't bring herself to wear back then can now have a new life with someone else. She remarks that that's all right in the end. She comments how she's jealous that Mahiro looks great in girly stuff, while Mahiro sweats saying that that's nothing to be happy about.

Trivia

 * Considering that Mihari has her signature hair clip that Mahiro gave her as a reward for doing well on a test during the flashback, this indicates that the flashback occurred after the flashback seen in "Mihari and Her Onii-Chan".
