The Haunting Ghost Husband

My name is Zuo Ran, and I'm a Didi driver. On the night of the Ghost Festival, a mysterious man got into my car. The place he wanted to go was a cremation ground! That night, I went through the most terrifying experience of my life. I thought he would disappear from my world for good, but instead he kept intruding on my life again and again. After meeting him, I nearly died when something was thrown from a great height, and even got caught up in a headless corpse case. Who is that man, and why is he plotting against me?
