Ok. So. I thougth about this story since i finished it and the sequel just popped up. I was thinking about "what if hanji travelled into the aot universe?" And then i made a full scenerio in my head lemme tell ya what was it about:
-it was a casual day for the survey corps yesterday they just came from a not very succeding but good mission, but there is only one thing wrong here. Thats when the whole thing with Hange and maybe with levi and moblit coming in. In sma4y that hange slowly got tired out life bc of not having y/n anymore and one day they just ended it all but they weren't expecting to wake up at a table someone shaking them awake. Hange was confused at this point but they wanted to see who was being rude by waking them up. Then boom it's y/n, but not the sick one, the healty obe who workes as a corps member just like hange. Hange is pretty schoked but can say anything bc yn is already telling them to wake up and get to breakfast( then she rushes out of the room leaving hange confused)
Hamge ofc thinking its a dream goes out to eat then she meets with levi and moblit and thats when mainly everything gets figured out. Hange is like screaming-talking to the boys telling them that somehow yn is alive and well amd she saw it with their own eyes. Ofc the boys first dont believe her but suddenly yn walks away infront of the table waving them.
That would be start. I imained that the first park would be from Hanges pov and the second is from yn's.
Here comes the little twist. Yn soul got into the aot body of hers after the aot yn got into a really bad accident. BUT 4 years before this /\. She already had a good realitionship with hange but she didnt wanted to ruin it by having a cruah on them so she slowly falled into grief. By her dying but still having the memories of her past she's to smart not to notice that hange started their morning off differently. Neither hange or yn knowing that both of them know about each other memories i think the story can evolve.
