I think adult not even dating Mizurui should get engaged and break up immediately. Just for the bit. One day, completely out of the blue, no explanation, Mizuki proposes that they be ex-fiancées, and without missing a beat Rui proposes with a ring pop that she of course just has on her, and then they break up the second Mizuki finishes eating the candy on her ring. And then they casually refer to each other as their ex-fiancée whenever funniest, and make up a different story any time anyone asks when and how and why the hell that happened without anyone knowing.

Ex-fiancées mizurui, obsessed with the image of costume jewelry. Like after their initial ring-pop engagement and subsequent annulment upon consumption, Rui finds herself buying dirt cheap costume jewelry for a show, and she sees a pretty piece that reminds her of Mizuki. So she gets it, and next time she sees Mizuki she casually puts a velvet box in her hands, to Mizuki’s bewilderment at Rui giving her nice(-looking) actual jewelry before Rui specifies it’s costume, to which she sighs an oh thank god. “Is this as another proposal?” “I suppose you could take it that way.” So now they’re engaged again. Mizuki makes her an accessory/piece in return, and giving it to Rui frames it as a proposal again. “I’m flattered, Mizuki, but I don’t think you can propose if we’re already engaged?” “Wait, I totally forgot about that. Let’s break up.” “Aw, alright.” “Now that we’re officially broken up, will you marry me, Rui?” “Hehe. Sure.” So now the bit is getting engaged every single time they give each other a gift, only partially keeping track of if they were engaged or not beforehand so they also break up immediately before the proposal. And often after.

Friends in solitude to friends to situationship to ex-fiancées Mizurui. Progression of their relationship over like nearly a decade. I’m just so deeply enamoured with them not dating but not not dating and then making the decision to firmly establish themselves as ex-fiancées for the bit as the first time putting any romantic subtext into words, and now their excuse for anything bluntly romantic is that it’s performance art. Lingering glances behind closed doors to PDA for clout in one easy step. Here’s how fake dating Mizurui can win, fake divorce.

Adult not really dating Mizurui where provided they’re both otherwise unentangled, their relationship status is whatever’s funniest slash most convenient, lowkey giving off the impression to their friends that they’re one of those deeply unstable couples who break up and get back together at the drop of a hat, because they don’t really care to explain what’s actually up with them, and it’s a great way to farm pity slash unamusement with excuses like “sorry, me and [the other] are on the rocks rn so I actually can’t go do that thing cause I have to buy a dozen roses and see if she’ll find it in her heart to forgive me, byeee”

I really like future ex-fiancées (not necessarily dating beforehand, just for the bit) Mizurui because it’s kind of an even more unfailing relationship state than them actually getting married is, in a certain sense. They can’t get un-unengaged (short of getting engaged again lol), and so choosing to define their relationship by a perceived “fail state” while remaining on genuinely great terms is sort of the ultimate extension of their “can’t get rid of you”ism. Like a permanent mark of the importance they’ve had to each other, regardless of the specific form, regardless of where their lives take them past that point. And the idea of a shotgun divorce like less than an hour after the proposal, just to be able to say that they’re ex-fiancées, is truly so fucking hilarious to me.

Deeply pondering pseudo-romantic aromantic Mizurui at the moment….. very fun. I think they’re well and truly exactly the type to get platonically married for tax benefits. Reaction to being proposed to over text: “? Sure.” also I think they’re exactly the type to get platonically divorced once the purpose of the marriage dissolves. And then introduce the other as their ex-spouse any time possible because it’s the funniest relationship status to have with someone you’re still on good terms with
