In 2157 AD, after humans discovered that tellurium isotopes can store memories, the way criminal punishment was completely changed - felons were no longer imprisoned, but were "removed": their memories were completely erased and sent to a strange city to start a new life. Tai Zhu is the best executor of the Memory Correction Bureau. He has personally performed more than 300 star transfer cases in the past eight years. Until one morning when he woke up, he found a strange woman lying on his pillow, who claimed to be his wife of five years. What's even more strange is that the name on his work permit changed to "Tai Xuan", but the person "Tai Zhu" was not found in the system. When he began to trace the truth, he found that the memories of all his colleagues were different from his. Only the withered blue plant on the table and a remaining memory that could not be deleted told him that he had loved a woman named Xin Li deeply. Her last words before disappearing were - "Don't believe Ji Entropy, don't believe yourself."
