Lost in Limbo (WWI/WWII Countryhumans X Reader)

Y/N is just getting over a tough breakup..............when a mysterious portal appears in her room. She steps through and finds herself in a mansion...........full of countryhumans!?!?!? Except these countryhumans have been dead for a long time............so how did they get here!?!??! How did you get here!?!??!?! As y/n tries to find out the truth a romance brews between her and the other countries. This is sort of canon to my RusAme story but not really.
(Inspired by the stories Old Countryhumans X Reader by Scp-Whirl049 and Bacterial Contamination by ChimeraOblivion. The plot will be a bit different but the credit goes to them for the idea)
