For this topic again, now I would like to recommand this dojin by 펩PEP-san (@ansdj8181).
This 80-page doujinshi is mostly written from Sakiko's POV, with nearly 50 pages focusing solely on the intricate details, the inner feelings, and the playful back-and-forth between Uisaki as they walk home sharing an umbrella. Since Uika didn't bring one, Sakiko shares hers. But we all know how sharing an umbrella goes with these two: Uika takes over the umbrella and tilts it completely to Sakiko's side, getting her own shoulder and school bag soaking wet. Sakiko gets mad and insists they hold it evenly, but Uika refuses, saying it’s her own fault for forgetting her umbrella and dragging Sakiko into this. After pushing back and forth a few times, Sakiko gets genuinely upset, and they end up arguing...
It’s such a beautifully delicate and well-written story. Honestly, whenever people talk about Uisaki fighting, they really need to check out this book. The way the author interprets and handles their relationship is so spot-on—it makes you go, "Yep, they would absolutely react like this!
I once thought about what a fight between Uika and Sakiko might be like. It would probably start with something trivial, almost playful, but gradually become more serious until it turned into a real argument.
Ironically, the reason they end up fighting would be because they care about each other. Uika always wants to look after Sakiko more, so she does things out of consideration for her, but Sakiko hates seeing Uika constantly being the one who sacrifices something, and wishes that Uika would think a little more about herself for once. So they end up arguing. Uika says, “I’m the one involved, and I’m fine with it, so why does it bother you so much, Sakichan?” Sakiko replies, “Why are you so stubborn, Uika? Wouldn’t doing what I say be what’s best for me?” The argument gets pretty heated. Anyway, after a serious fight, once they’ve both calmed down, they make up—and then it would be nice if they had rough, passionate sex.
To be honest, that last sentence is the real reason I wrote all of this.
