Two heroines, both reborn, with Systems that counter each other. A cool and composed upperclassman returns to life with an “Investment Returns System.” Determined to plan calmly, she casts a wide net and invests in everything, waiting for hundredfold returns and the peak of success. But then she discovers that her most important “investment,” a goofy underclassman, has also been reborn and is bound to an “Emotional Scam System” designed specifically to counter hers. The underclassman’s goal is to squeeze the most extreme emotional reactions out of her upperclassman in the most outrageous ways possible: flustered outrage, shock, and embarrassment, all in exchange for rewards. And so begins a battle between “I’m going to invest calmly” and “I’m going to make you completely lose it,” as the two love and fight in equal measure.
