It's been almost ten years since the world turned into a ghost of its former self. There is devastation and desolation everywhere, moss covers the asphalt and the walls of houses, and at night those who once lived here take to the streets. Helpless puppets of the virus or, as they are called, infected. Is it possible to survive in this terrifying and empty world? Firmino survives in a small town called Villasile. He is not afraid to become infected and share the fate of the unfortunate people hiding in flocks in basements; he is afraid of going crazy from loneliness. But all his fears will fade the day he meets a 13-year-old boy named Alex on his way. The meeting that became the source of Firmino's happiness and unhappiness would change him forever. After all, sometimes even the most innocent smile is fraught with darkness.
