In the near future, memories can be repaired, edited or even deleted. The "Eternal Heart" company is established on the isolated "Quiet Island" to provide customers with top-notch memory healing services. Lin Mo is the company's best memory restorer. He is calm and precise, and can repair any broken memory seamlessly. Until he met a patient codenamed "A Yuan", a "wrong" memory in her mind that could not be deleted, eroding the logic of the system like a virus. In the process of searching for the truth, Lin Mo discovered that this isolated island of memory was floating on an ocean called "forgetfulness", and he himself had long been a part of this ocean. He must make the final choice between cold duty and awakened humanity.
