This is sort of a foundation for their relationship, to my taste (☝🏻), in the basic AU, where everyone is alive, but I'll probably use this outline in other AUs as well, lol. I tied the pilot and Aidairo's other projects into canon relationships.
There would be too many lines in the left corner if I listed all the relationships. However, it turns out that Yugi, Nene, Koyuki, and Shijima girls are all friends in a certain way. The lines can easily reveal other relationships; Shijima might know Minamoto through the girls and Yugi. Tsukasa, on the other hand, has a wide variety of acquaintances.
As for the various trios, I've thrown out canon Aoi, sorry, but yeah. I'm perfectly fine without canon Aoi; she's only useful to those who love her, but I don't love her and there's nothing I can do about it. Without her, canon Akane's malicious intentions are dormant, Nene can be friends with other girls normally, without the emotional rollercoaster. I can also create difficult and short-lived relationships of this type with the crossover Chitose and Lily (with pilot Aoi, for example) and stuff like... somehow, without canon Aoi, everything works just fine. Pilot Aoi is a flighty brat, not even enough to be the queen of the school, just that way, and her toxic friendships with the girls are explained by the fact that she doesn't take it seriously and wants to be a pick me, lol. Now that's what interests me. And the two Akane exist simultaneously because one is that pathetic yandere, and the other is a bestie for Teru, Kako, and Mirai, lol. He has dynamics that I don't want to throw away. Canon Akane is the version of him where he behaves adequately (that is, his entire characterization outside of the Aoi crush (though he can still be scary, just for different reasons, he's still that weirdo, I guess), pilot Akane is that same really creepy moe guy ( ◜‿◝ ), and then there are Lemonaoikane. I also changed their names so it would be different from canon and it would be immediately clear that this is someone's AU, lol. Akanecest of a human and a mystery? Akanecest of a pilot and canon lol.
Chitose and Hatori are characters from another Aidairo one-shot. Money, Maidens, Love, and Innocence. The npc girl is one of those recurring npcs in tbhk and all the other projects, and she seems to have interacted with Chitose, so they could have been friends. I think the KaruLily and Chitose squad could be from a different school, like in the meme "different school and everything is the same, but in a different font" or, as they say, a distorted mirror image of the main cast (literally two different Akane).
Hakusumi are siblings, yes, but it's not because I think their pairing is bad or problematic, it's just that I don't see any spark in it for myself, whereas platonically it's more viable. They didn't quite touch me, but they're cute in their own right. Sakura is kind of Hakubo's boss, plus she and some of the cast, well, including Sumire herself, are older than the main cast (like Yugi, Kou, etc.). Natsu isn't a loner, it's just that things are more complicated than just "complicated"... maybe he just secretly knows everyone here lol. If you drew lines from his corner, the whole page would be covered with them.
The color yellow, which signifies "it's complicated," doesn't just mean "they have romantic problems," but also something that's truly hard to describe, because I usually perceive Sakuhiko as a marriage of convenience, and it's unclear how that will affect other AUs. And in Mitsukou, Kou might actually be harassing Mitsuba with his first toxic crush... and then Mitsuba will come out of that relationship traumatized. And that would be a pretty easy option for him... I'm sorru again I don't believe in Kou's innocence (although there is no point in apologizing for the truth, is there?)
It's also surprisingly that the tbhk fandom doesn't have the "two kids are supposed to be friends" trope, because Tiara and Mirai are literally... so why not 😔
I'm posting this so that there's an explanation for why my Aoikane are so weird (they're from the pilot), or why this or that (yeah, Tsukasa/OC, toxic Mitsukou, etc).
