I enjoy stuff set in universes like FFXIV, Naruto, etc but I prefer the main cast to be side characters or not at all in the case of FFXIV unless your character has a reason to interact lol
The scary thing for me as a whole about seeking rp partners is simply finding someone who wants the same stuff. It's personal to share writing sometimes so it can be embarrassing and I've never sought out a partner like this before. I met people organically in open spaces and it went further...
