This is not a story about how technology replaces humans, but a story about how technology can help us find ourselves again in the most unexpected ways. When Cheng Yue fell into emotional ruins, a smart pet named "Xiao Nuan" entered her life. It is not just a collection of codes and algorithms, but also a loyal partner and an honest mirror. This book explores the boundaries between loneliness and connection, trauma and healing in the digital age. It asks us: When artificial intelligence can understand not only our habits but also our hearts, will the shape of love expand? I hope you find warmth and the courage to start over in this story.
