Zero to Overlord

Wyatt dies at forty, shortly after leaving prison, having led a gang whose members he got locked up and whose fallout he blames for his mother's death. He wakes at eighteen, back in vocational college, bound to a system that rewards late success. He works out that his first girlfriend Zoe has been setting him up, exposes what she was planning and drops her. He pulls his friends out of gang life and starts a food delivery platform, Wildfire Tech, running it out of the university district. Along the way he helps a cold, top-ranked student who is afraid of men and who later becomes a force in technology, and he goes into business with the daughter of a wealthy family who has left home to start out on her own. The Green Dragon gang and its leader Sun push back on the delivery business, and so does Zhao Haicheng, the son of the rich Zhao family in Haicheng.
