Does anyone know the name of the novel about the male protagonist's life of hard work? I've read it before.

The first half of the novel was about the male protagonist's growth stage. In university, he foolishly pursued a girl, but the girl was very rich and had status! The girl only felt that this boy was very good to her and gradually fell in love with him.
In the middle of the novel, the male protagonist and the girl got together, but because they had just entered society, friction began to arise in their lives. The boy left the girl and stayed outside for a long time like a madman. In the end, the male protagonist helplessly began to help his childhood friend (who was already a big boss) write an advertisement for medical and health products, but the salary was very low! Through his understanding of his boss's company, the male protagonist threatened his boss with the company's illegal accounts and demanded millions!
At the end of the novel, the male protagonist used the millions to start his own business. He bought a pharmaceutical company that was about to close down and started a new development! Then, he booked the most luxurious cruise ship in Shanghai and invited celebrities from all walks of life to participate in his activities. He did a good job of promoting his pharmaceutical company! In a few years, the male protagonist became a millionaire! However, he still couldn't forget the girl from that time. However, the girl had already married a celebrity!
