Yu Qinghuan, who was abandoned by her adoptive parents after squeezing all her value out of her, came back from the dead and found that she was the miserable supporting actress in a sadistic novel. After awakening, she no longer follows the plot, but uses her unusual economic game theory thinking to regard all emotions and relationships as calculable game models. On the road to revenge and counterattack, she instead attracts the domineering male protagonist who was originally the heroine of the original book. This is a top-notch game of IQ and EQ, and also an adventure about whether "sincerity" can be calculated.
