My Cashback System Comeback

After failing to find success in a big city, returning migrant Leo Lee moves back to his small town. A random kind act leads him to meet alt-girls Chloe Hayes and Yara Sutton, and he accidentally activates a consumption cashback system: every time he spends money on a woman, he gets a high rebate based on her satisfaction. Leo then uses the system to spend on the easily pleased alt-girls, quickly accumulates wealth, gains genuine affection, and humiliates various malicious villains along the way, completing a life comeback in the small town.
