Is there such a person in this world? He/she is so special and unique to you. As long as he/she appears, it is like the cool breeze in summer or the warm sun in winter.
To him, she is the sweetest snack in the world, and to her, he is the unique patron saint in the world.
The youngest son of the demon god, because he was greedy for the scent of the blood of a human girl, he stayed in the human world for a long time and became a demon, living on human blood. Since then, he has been collecting the blood of different girls in the human world. Until he met Fan Xin, he could no longer accept the scent and blood of other girls.
That day he appeared in front of Fan Xin like a god. Even if she later found out that he was a devil and not a god, she still believed that he would protect her instead of harming her.
Concept: The story of a girl with a strange smell in her blood and a bloodthirsty demon
