reborn au sakura is fantastic and i love her!! tori's apprentice in chaos gremlinness!! however i do privately think she might not be that into sasuke in a situation where he ISNT The Last Uchiha (tm), motivated beyond his years, a broody and tragic lone wolf? like regular non-massacre sasuke seems like he might be just Some Guy with a huge and quite cute brother complex? (though i guess the konoha-wide uchiha obsession might compensate for all that and still make him the class hottie..)
i've thought about this a bit for other non-massacre AUs, but ultimately i think sasuke would still be the coolest kid in class. an absurdly large portion of female characters that sasuke meets remark on how attractive he is, even not knowing his mysterious and cool anime background, so i think.... i think sasuke is just canonically really really good-looking. we saw enough of his "younger less talented sibling" complex pre-massacre that i think he'd still be highly motivated to be the best in class (albeit not AS motivated as in canon), plus it's implied sasuke has a lot of natural talent/power on top of that motivation. so i think while he'd have less of his mysterious and broody ~wow~ factor, sasuke would still be the prettiest boy in school AND at the top of his class (or at least consistently duking it out with whoever #2 was). i think he'd still be the #1 target of young school girl crushes, although it might be less intense
i also like keeping sakura's academy years crush on him just as a way for her to feel more ~sakura~ even in an au. although i personally like them better as friends so in most AUs i'd have her grow out of it pretty quickly (or maybe write her as unfortunately very physically attracted to him even as she grows less impressed with her personality).... he's still an excuse for her to feud with ino though, which i like playing with.
also with her direction in reborn au, at some point it's not even about her thinking he's cute. it's about making boys fight over her :)
If Sanctuary Moon is a TV show in Teenage Exocolonist, then that means it takes place in the same universe as The Murderbot Diaries. Also, I'm having a very Murderbot moment in that I really think the introduction of a heroic Secunit would fix a lot of the colony's problems.
