An apprentice priest under the protection of the princess. An orphan abandoned in a mysterious forest. And... She, Freya, who sees others' emotions as colors. Positive emotions are gold. Negative emotions are black. Her mysterious ability was her own secret. During her pilgrimage to become a priest, Freya woke up in a strange man's bed. "You... What are you?" the man, Aran, asked threateningly, his red eyes shining. He looked exactly like the hero in the mural Freya had seen since she was a child, and even had the same name. But Aran did not show any color of emotions. At first, she thought it was a dream. She thought she was having strange dreams multiple times. But it seems... It's not a dream. Who is this man? Where do I go every night? Why is it me? (Source: Kakao Entertainment Corp., translated)
