Lu Mingfei received a blank letter without a postmark at the bottom of the old box. The rain fell on the corner of the letter, and a line of words emerged: She held the umbrella for you, but she forgot. In order to retrieve the rainy night that was deleted from the world, he traced the fragmented pages of the future, the Kassel archives and a black umbrella that should not exist. Nono remembers nothing, not even that she chased him into the rain. Everyone advised him to stop, because every time he retrieved a memory, someone would become thinner and disappear from reality. But this time, Lu Mingfei didn't want to back away with a smile. If she had held an umbrella for him, let him walk through the rainy night and give her that companionship.
What the hell.
