The sea in Cliff Town is always gray and blue, and the waves carry a salty wind, beating the fate of the forbidden love of the "sisters". Seraphina's white pupils were accused of "Satan's Mark", and the eye patch could not hide the malice of the world; Vespera's icy blue eyes were burning with wildness, and she dared to make enemies of the whole world to protect her sister - they were "heretics" in the words of the priest, and "bastards" spurned by the people in the town. Only each other's embrace was the only light in the dark night.
