Ask for the title of a romance novel

The story was roughly as follows: When the male protagonist was young, his father was an alcoholic. He treated him and his mother badly. After a fire, he escaped and was adopted by a rich family. However, he hated alcoholics the most. The female protagonist loved money very much. When he was young, his father was also an alcoholic. He became the male protagonist's driver. Their first encounter was when the female protagonist was bullying a boy. Her father drove past with the male protagonist. The driver shouted at the female protagonist and looked at the girl through the black glass boy...
In high school, they became very good friends.(The female lead loved money very much and even cut off her long hair to sell for money, but the male lead did not allow her to do so again.) Later, the man went abroad (of course, she had contact with the female lead). A few years later, the man returned. When the female lead realized that she had fallen in love with the male lead, she kidnapped him. Not long after, the female lead disappeared. She was killed and fell off a cliff. She lost her memory and changed her name to Ningning. The male lead also found her. Once, the female lead fell down the stairs and regained her memory. At this time, she was also pregnant with the male lead's child...
It's modern, and amnesia is only a small part of the book (a little later). Most of the female protagonists have another name, I think it's called something small (I can't remember, three words)
