The top wealthy Shen family collapsed overnight. The eldest daughter Shen Qingli fell from the clouds and transferred to an ordinary university. In order to repay the huge debt and regain everything, she was forced to bind to the "red line selection system". The mission goal was to please and gain 100% favorability from the "villain" recognized by the whole school - Lu Jin, a poor transfer student with a gloomy temperament and rumored to be very fierce in fights. Each time a task is triggered, the system will give three different options, corresponding to different interaction methods, rewards and relationship progress. Shen Qingli was forced to let go of her arrogance. From the initial awkward treatment, she gradually discovered the delicacy and tenderness under Lu Jin's cold appearance. She was even more shocked to realize that he was the mysterious person who secretly continued to fund her studies anonymously, and the food blogger "Jin Ye" with amazing cooking skills. The two-way secret love grows in the "choices" again and again. Lu Jin has long recognized Shen Qingli as the girl he saved when he was young and has missed him for many years. All the "darkness" and "approach" are his clumsy and passionate approaches. When the conspiracy of the Shen family's bankruptcy was uncovered by the two of them, Lu Jin's hidden prominent family background (not a traditional wealthy family, but a top scientific research/art family) was also exposed. In the end, Shen Qingli relied on the help of the system and her own wisdom to successfully counterattack, while Lu Jin used delicious food that blended into his heart and unreserved protection, completely doting on her and becoming the only one in the palm of his hand.
