Cheng Yang, the most powerful person who has suffered from insomnia and nightmares all year round, will he be able to sleep peacefully alone when his heart knot is untied.
Yang Lei often dreams of a vague figure, but the person in the dream gradually overlaps with Cheng Yang.
Concept: People who have nightmares just can't forget the past. People who forget the past may still be living in dreams.
