She is the abandoned second young lady of a family of demon slayers. She was born without Yin and Yang eyes and is considered a useless person in the eyes of her tribe. He is the nine-tailed fox prince of the demon tribe. He was saved from a trap by her when he was young. Fifteen years later, he transformed into a servant and sneaked into the Qing family to repay his kindness, only to find that she was living alone in a dilapidated side courtyard, forgotten by her family, and struggling to survive by self-taught medical skills.
He concealed his demonic aura and stayed by her side, repairing windows, drying medicine, serving tea and water for her, and watching the stars with her under the apricot tree. She thought her life would go on like this, and he thought that as long as he hid his identity, he could stay with her forever.
But the hundred-year peace between the human demons was finally broken. The Demon Suppressing Division raised its butcher's knife, and the two worlds that once lived in harmony were pushed into opposition to each other. Humans and monsters have different paths, but those two hearts that refuse to let go, insist on giving it a try.
