Princess x Knight/Bodyguard is a favorite of mine, it's oddly hard to find!pretty simple: princess X bodyguard or nerd X bad boy. i'd also love to do an age gap thing someday...
Honestly feel this. Nothing ahaomat the super smutty stuff, it has its place but I'm very average in that regardPlot-centric occult fantasy with no small helping of what I would call spiced French vanilla smut. I am a chameleon as far as giving other people what they like convincingly, but I have nothing odd about myself at my core. I just love steamy romance with character development.
I do enjoy the Fate series. I'm not the most well-versed in Fate as a whole, but I've seen most aspects of it (Such as BB, one of my favorite Fate Characters, and the Sakura 7). A lot of those that you posted sound interesting. I'm mainly only familiar with the Isekai side of what you mentioned and Fate, though.Fandoms. Especially craving an RP based on series like Fate/TYPE-MOON, Symphogear, Idolm@ster, Love Live!, BanG Dream, Touhou, Sailor Moon and Princess Connect Re: Dive. Also started to play Honkai Star Rail so maybe something based on it depending how much I get into it.
Also been in the mood of doing some kind of original villainess or isekai villainess play. Have a few more specific ideas for this that I need to write down. Villainess-characters have become one of my favorite characters to play as or against so anything including them, whether it's a typical fantasy-setting, isekai-setting, otome-game based or somethin completely different and out there.
