Everyone is born into a blank world. As they grow up, the world fills up with everything they love, including people and things.
A long time ago, Duofu's world was very empty. In fact, Duofu liked some things, but he just didn't love them enough. Whether it's with objects or people.
I don't know when some people quietly broke into Duofu's world inadvertently. Some people wandered around in Duofu's world and couldn't stop; some shed tears silently in the corners of the world; and some people disappeared from the world forever, leaving only a portrait of Duofu engraved in their hearts.
Even when Duofu was lying on the hospital bed, he still smiled and said, "The most stupid thing I have ever done in my life is to let those lunatics in."
