In the near future where technology can weave, tamper with or even erase memories, memory landscaper Su Wan is a legend at the top of the industry. She can customize the most perfect golden age for her clients and repair the most painful mental trauma, but she is helpless about an accident three years ago and the subsequent blank memory. She is like a prisoner living in a gorgeous but windowless room, describing the scenery outside the window for others, but she can't see a trace of sunshine herself.
A "non-existent commission" brought a special man, Lin Shen, into her world. He is a relic organizer, and his job is to organize the relics of the deceased and find the remaining warmth of life in the forgotten old things. He knocked on the door of Su Wan's memory studio with a unique ginkgo leaf specimen and a mystery about the "Forbidden City".
When the cold and precise memory data meets the warm and simple physical relics; when the artificially woven "perfect" past collides with the dusty fragments of reality, a journey of pursuit spanning virtuality and reality begins. Su Wan was forced to step out of the safety barrier she had built and dive into the abyss of memory with Lin Shen. They discovered that the missing pieces of each other's puzzle pieces were exactly the keys to each other's world. And that mysterious "forbidden city" not only buries their common past, but also hides a shocking secret that can subvert the entire memory industry.
