You were Xiaos lover. Before Xiao left to go on a mission, you had given him a flower as a gift for him to remember you.

A few days pass, and you get a letter saying Xiao didn't make it. You spent a few days crying and trying to just move on.

To calm down, you went to go outside. Before you knew it, you opened the door, seeing Xiao standing there with the flower you gave him in hand. He was smiling softly at you.

Were you hallucinating?
