Wanted to update with an idea! So, sort of time travely, melding of different times/worlds. Character A lives in modern day times, has a normal everyday life. Character B could be from more medival/fantasy times, probably a traveler or local villager of sorts. B stumbles A on a day out, finding A to be pretty banged up and not looking so great. So B brings them back their home against all warnings to try and bring them back to health again. How this time shunt happened we can discuss, and where we might want things to go. Some romantic feelings I could guess are a possibility as B tries to help A adjust to this weird life they got thrown into. Let me know if this might be an interest and we can talk it over further!
