The Demon Queen A Jin has been searching for her daughter for three thousand years. She mistakenly identifies Su Li, a mortal child who was mistreated by her biological mother Yan Zhiyun, in a cold alley of the human world. She regards her as a lost bloodline and joins her in the Demon Palace as a treasure. Su Li, who was once covered in bruises and as timid as a frightened bird, gradually faded away from her scars under A Jin's gentle protection and blossomed into a lively and cheerful person, thinking that she had finally found an eternal harbor.
However, the truth about her bloodline was finally revealed - Su Li was actually a mortal, and the demonic energy of the demon palace was quietly eroding her life. In order to protect Su Li, A Jin did not hesitate to waste thousands of years of original demonic energy and used the forbidden magic of the demon to change his destiny. The maid Qing He even sacrificed her life to help Su Li successfully transform into a demon.
When the pain of the past is covered by the warmth of the devil's palace, when the bond of misunderstanding is stronger than the bond of blood, the mother-daughter love between A Jin and Su Li has already taken root in the life and death choices. However, the true girl who has not been found for thousands of years is still wandering in the three realms. What kind of waves will this "misrecognition" in the name of love cause in the future? And can Su Li stay forever in the devil's palace that changed her fate and become A Jin's only little princess?
