Her Ex Is a Tech Tycoon

Chad Kelly worked three jobs so that his wife and son could live well. He was diagnosed with lung cancer at an advanced stage. When he got home he found that his wife was now with a rich friend of his from college, and that his son called the man his father. The two of them called him poor and incapable and laughed at him, and they threatened him with divorce. Chad vomited blood and died. He woke up ten years younger. This time he did not go with his wife when she moved to the provinces, and he asked her for a divorce. He put his time into research. He worked on lithium battery technology with what he remembered from the first life, and he tested a design that could change the car industry.
