The Old Book Sent by the Wind to the World

There is a profession in the world that no one knows about, called Shi Suiren. The regrets, unspoken words, missed people, and late farewells of all people in the world will all turn into lint, floating in the wind, rain, and old streets of the city. The person who picks up the old age can see the old catkins, catch the old catkins, and seal the old catkins. They do not travel through time, defy nature, or cultivate immortality, they only do one thing: Collect all the betrayed tenderness in the world, and make up for the regretful people.
