You're technically right. Fiance is definitely considered a singular entity in English, but we decided on this name as mostly a play on words. Fiances doesn't exactly make sense, as there is no true "pair" of fiance. In French, fiancé is for a man who is engaged, while fiancée corresponds to the woman. When you refer to two people who are engaged, you usually call them individually by that, or just "engaged". (If you wanna read more about the specifics, you can have a look here: https://en.wiktionary.org/wiki/fianc%C3%A9).

As for the last thing, I regret to inform you that when she quit osu! around a month ago, she deleted all of her mapsets. Every one. The old mapsets had some that were submitted under her old name(s), either Kaitlin or Fii, and all of her ranked maps or gds reflect their previous names.
Hopefully this explains it a bit more, I know it's a bit odd but yeah! If you have more questions feel free to ask, it can be pretty confusing for people who don't know the entirety of her and I xd
