In 1876, during the last Carlos War in Spain, a girl named Amaya in the orphanage was rescued by a mysterious woman living in the depths of the forest. Amaya, who was seriously injured and dying, thought she had seen the angel who took her to heaven, but at dawn the next day, she soon found that the strange woman had given her eternal life in exchange for her company. Amaya had to spend her life chatting in the little girl's body, spending long years with loneliness until she met Candido. Although she lived a hard life, Candido took her home as if she were her own. From then on, the girl began to struggle with fate, hoping to restore her broken life. By Deep Shadow
