Falling in Love with Ghost

I met a girl who claimed to be a ghost, but I only had 3 months left in my life. The girl asked me to accompany her to complete some things. In the process, we learned about each other's true identity. "It turns out she had always loved me before she was alive." "It turns out we can't find the light" "It turns out we redeemed each other" This is a love affair that will never end from the beginning. I hope we can meet again in the next world.
