wah, i'm glad to hear that people are enjoying my ratiorine family hc's 😭💖 oh, you bet that aventurine did joke about that, and when he finds out he's having twins AGAIN for the THIRD time in row, he's like staring at veritas with a deadpanned face, "what are the odds." and the latter, clearly smug, just says "hey, i'm not the one with the gambling luck here." 🤣🤣 you can imagine all kinds of chaos happening in their house with 6 kids! i have plenty of nieces and nephews, plus being a kindergarten teacher, i can definitely confirm that it's never a quiet moment in their house, but ratiorine wouldn't have it any other way. ❤ in fact, they're cuddling up on a couch as they watch their children playing and bonding well together. it's such a sweet intimate moment until SURPRISINGLY it's aventurine who is like, "maybe we should go for another round?" cue ratio's side-eye while churin is just looking at him innocently. ratiorine singlehandedly repopulating the avgins 😂

👀 oh this is feeding me a lot of ideas. let's go all the way back before they started dating, shall we? but ABSOLUTELY, he has a whole room in his house that's full of aventurine merch!!! he even got his hands on the limited edition, and in fact, i think ratio may even pick up photography to take pictures of churin (he probably has a fansite dedicated to him) but here's the thing. no one knows he's churin's fan. not even his students! he shows up to every concert and meet&greets always wearing his plaster head, but no one really bats an eye since he's not doing anything crazy (but just maybe he did creep out some people) and at some point, he is such a regular that the staff has recognized him, EVEN CHURIN RECOGNIZES HIM (its very hard to not ignore a man who is the only one to wear a statue head after all) and i think from there, aventurine is so very curious to get to know this fan of his, like man, what kind of job does he even have to keep up with all the events in aven's schedule?? in fact, how does he even have the free time????

... this turned out to be a longer answer than i expected but thank you for this delicious ask, I LOVE IT

i'm not quite sure about that, i don't think it changes much because sunday claimed that most things aventurine has answered under harmony's curse were nothing but falsehood and thus was punished as a result (with the 17 hours system) and as we know, aventurine genuinely did think that ratio dislikes him per his conversation with the harmony image— don't forget too that churin really said "to fool others, you need to fool yourself too." so.... yeah i think it may do a little to change sunday's mind. that said, at the end of the quest, i think it's strongly hinted that sunday actually knew that ratiorine was collaborating (since he told gallagher, "why do you think i just let him ran free afterwards and create a big scene in the auditorium which i took the liberty of clearing it up?")

hmmm, rtrn soulmate au... how about they each have their soulmate's eye color that automatically swaps back to their original own as soon as their eyes meet??? i think it'd be an interesting idea. since avgins are known for their unique eye color, i think dr ratio possessing them puts him in a spot where he firsthand witnesses discrimination they have to go through. he knows for sure the eye colors don't belong to him— one look at his parents is enough— and he'd also get comments like either "oh... your soulmate is a...?" or "tch, you vermin, get out of my way." (they may have mistaken him as an avgin due to the eye) and it just makes dr ratio even more protective of this soulmate he has never gotten to seen before.... and imagining when ratiorine first met, as soon as their eyes lock and swap, ratio was in complete awe as he stares stunned at churin. he had always thought the eye color itself is pretty, but seeing them in their full glory on aventurine... it was a whole another captivating sight to behold 🥺
