Two heroines, two lives + systems that defeat each other. The cool senior sister returned from rebirth, bound to the "investment return system", determined to calmly lay out her plans, cast a wide net and invest more, waiting for a hundredfold return, and reach the pinnacle of life. But he discovered that his most important "investment target", the school girl who was a charlatan, was also reborn, and was bound to an "emotional fraud system" specifically designed to defeat her. The goal of the school girl: to use the most outrageous method to extract the most extreme emotional value (breaking defense, shock, shame) from the school girl, and exchange for rewards. A love fight between "I want to invest calmly" and "I want you to break the defense" begins.
