This Fanfic takes place after Kaoris death in Your Lie in April.
Kaori had just died, like that and her spirit that was playing with Kōusei had faded away from him. She then arrived at what appeared to be the afterlife, a place which was always blue and somehow full of pianos, violins and to the surprise of Kaori traditional buildings and old football stadiums
Then two figures approached her.
A figure by the name of Lord Metcalfe of the dimension and Saki Arima
"Welcome to the afterlife Kaori" said Saki
"You must be Kōuseis mother, I'm Kaori" said Kaori
"I heard about what you've did and how you saved him from the darkness and with that, I say thank you" said Saki
"For that, you'll receive an award, you'll be brought back to life to be reunited with Kōusei, under one condition" said Lord Metcalfe
"What is it" said Kaori
"You will be first be brought back to life in 1980 in East Germany and you'll be serving as an East German Boarder Guard until the collapse of the Berlin Wall, you will not age in this time period and your body will be transported from its apparent slumber to you and and afterwards you will then reunite with Kōusei Arimia a year after you died at his house, in uniform" said Lord Metcalfe
"Ok, anything for Kōusei" said Kaori
Then Kaori felt herself disapperaing
"Goodbye Kaori, good luck" said both of them
She then opened her eyes and found herself in a bed in what appears to be in an army barracks
Then officers stormed in
"TIME TO WAKE UP COMRADES" screamed the officer as Kaori rushed into training uniform and went out of the sleeping quarters with her fellow recruits
The Next Chapter will be the beginning of Kaoris training and in the present, Spring has come and for Kōusei, a one without Kaori
