Billionaire He Huan was drunk and reborn, returning to his senior year of high school in 2007, taking back billions of his previous life's fortune with him. In order to rewrite his regrets and protect his family, he decided to find out the truth about his murder in his previous life. On campus, he counterattacked and got rid of his status as a bad student, and calmly dealt with interpersonal disputes; outside of campus, he seized the trend of the times, formed a joint venture investment layout, and even avoided a snowstorm in advance to save his mother. While his academic and business career took off in both directions, he unexpectedly discovered that his classmate Tang Yuanyuan was also a reborn person. The two joined forces to dig deeper into the deadly conspiracy hidden behind the years.
