Bai Xia woke up one day to find a ghost by his side that he couldn't get rid of.
The ghost called himself Ling Tong and said he had known Bai Xia when he was alive.
Bai Xia almost believed him, if not for the decades-old clothes Ling Tong was wearing.
So when Ling Tong said he was following Bai Xia to save him, Bai Xia didn't believe a word of it.
Then he died.
He transmigrated into a dream he had had over and over. In the dream, Ling Tong was a famous, rakish opera performer, while Bai Xia was a young master with a cat's head.
Bai Xia thought he was going mad. He tried again and again to save Ling Tong from his inevitable death. In the end, he drove Ling Tong to his death.
It turned out Ling Tong had been telling the truth.
They had known each other for a long time, destroying each other again and again in dreams where they tried to save one another.
This was a cycle of life and death, love and hate.
When love and hate cannot fade, neither of them can transcend it and live on alone.
Theme: Love dares not go too deep, for fear it may all be one grand dream.
