Liu Qing's last memory before his rebirth was that he was knocked away by a car.
He had once dreamed that he had been hit by a car, and it was his cousin, Ding Yongyuan, who had been Ding Yun's adopted son before he was reborn.
In that nightmare, he even dreamed that Ding Yun had a head full of white hair, had become very old, and was crying very sadly.
That nightmare had left a deep impression on him. A few months had passed, but he still remembered every detail of that nightmare very clearly.
Every time he recalled that nightmare, his resentment towards Ding Yun would lessen.
In that dream, Ding Yun was still very sad about his death.
The dream was so realistic that he believed that Ding Yun would be as sad as she was when she found out about his car accident.
Now that he heard Ding Yun talk about the dream as well and how she had cried so much that her pillow was wet when she woke up, he felt a little sad for some reason.
