In Xinhai City, the top amnesia specialist Shen Mo uses scalpel-like precision to peel away the painful past for clients. He sees memory as editable code and forgetting as the ultimate mercy. When a woman named Lin Xi commissioned him to delete everything about her late husband's Ark, it was supposed to be another ordinary business. However, when diving into the depths of those memories that should have been sad, what Silence touched was the warmth and love that could not be let go, as well as a dangerous secret that was deliberately encrypted. He discovered that what Lin Xi wanted to forget was not just sadness, but also a truth that could overturn the world. Silence is forced to make a choice between professional ethics and human conscience, and his choice will determine whether they sink into the sea of oblivion or keep the island of memory.
