Lin Mo is a senior sociopath who has to rehearse his dialogue three times even when buying water at a convenience store. His world consists of headphones, books and avoiding eye contact. He is so kind that he would apologize for trampling fallen leaves. His greatest wish is to become a quiet background in the city. However, a strange gray rain covering the world changed everything. The rain did not bring moisture, but instead sucked away all the sounds, and the world fell into a panic of aphasia. What's even weirder is that Lin Mo found that he was the only exception. He could hear voices, and even began to hear the desperate roars and waves of pain in other people's hearts. A mysterious being who calls himself an observer tells him that this silent plague is the awakening of ancient malice, and that only the purest spiritual resonance can heal the world. As a result, this young man, who found it more difficult to talk to strangers than to face the end, was forced to embark on the road to salvation. He must go into the center of the crowd, listen to the deepest suffering, and use his insignificant courage and innate kindness to respond, connect, and awaken the silent world.
