Ye Xuan is reborn back to 2004, coinciding with the rainy night when he was mistakenly identified as the rainy night serial fiend. After his rebirth, he immediately points out the true culprit to clear his own suspicion, activating the causality change system, and obtaining causality points for lucky draws by changing fates. In his previous life, he bitterly pursued campus belle Xiao Nanzhi and suffered ruthless rejection; in this life, Ye Xuan is no longer humble and flattering, devoting himself entirely to starting a business and making money, possessing tens of millions in net worth before graduation. Xiao Nanzhi, who rejected him in the past, is full of regret, letting go of her pride to actively chase him back. Lin Xitong, another campus belle from a different school saved by Ye Xuan, also boldly pursues him, with two romantic fates following one after another.
