Miles Shen was once wealthy and well-regarded, but his life changed when his family's business failed, leaving him in debt and abandoned by his girlfriend. At his lowest point, he receives a special system called the "Perfect Life System." According to its rules, if he spends money on a girl who has an affection level above 60 toward him, he earns twice the amount he spent. Using this system, Miles begins spending freely, and instead of his finances worsening, his wealth increases. He continues to use this method, allowing him to rebuild his life while others would struggle with such spending habits.
