Winnie, a graduate student in folklore, breaks into the Forbidden City of Vendro, a forbidden place in Eastern Europe, to complete her thesis.
In the rainy night, she met Karen, the eternal prince who had no shadow or reflection.
First embrace, blood contract, life and death binding - she became the only container for him to escape the thousand-year sunlight curse.
Paranoid possession gradually turns into true love, but the conspiracy is also quietly approaching:
The Duke who covets the throne, the hunter who has taken revenge for generations, and the truth about the blood contract that has been buried for thousands of years...
He said: "I have lived for 3,200 years and have never regretted signing this blood contract with you."
She said: "I will not break the blood contract. I will bear this curse with you and stay together forever."
After thousands of years of eternal night, we finally have a return date because of each other.
