In the endless sea of fire and sand, a castle that can only be seen in hallucinations emerges from the depths of the desert. Su Jin, who was born on the border of quicksand, carries the "afterimage of fire" passed down from generation to generation and embarks on a journey to find the phantom castle. She was eager to solve the mystery of her mother's disappearance, but found that the castle was woven from the memories of the exiles, and that time, space and reality were intertwined under the flames. The blazing flames of the desert are not only a test, but also a temptation - every step makes Su Jin struggle between losing herself and liberating the truth. She must choose between the rift between phantom and reality, not only to protect the hope burning in her heart, but also to face the secret that she once could not admit. In the fire of the secret realm, Su Jin's footsteps turned into flames, illuminating those forgotten stories and igniting new life above the sea of sand.
