In late autumn in the south, there is always a damp coolness. The paulownia leaves outside the window rustled in the wind, and the withered yellow leaves twirled and fell onto the terrace of the apartment. Lin Wan, with a somewhat tired body, returned home. The sensor lights at the entrance hall lit up one by one as she walked, as if a group of sensible elves were welcoming the hostess's return. This day was not an easy one.
