Ran Tang was working overtime one second, and the next second she transmigrated into the poor ex-girlfriend of the male lead Shi Yan, while also bound to a mysterious system whose task was to walk away unscathed in an agreement worth ten million. Socially anxious and honest, she only wanted to act out this play well according to agreement and then part ways. Who knew that the aloof, cold, and for many years single-from-birth Shi Yan would not only refuse to be indifferent and distant according to routine, but step by step break the rules to accompany her to eat roadside spicy hot pot, help her deal with water pipes late at night, take her home, and take the initiative to hold her hand, getting closer and closer. Said to be taking what each needs, how come the male lead instead fell in love first? This romance starting from an agreement has long turned into reality, sweet to the point of intoxication.
