On a stormy night, three-and-a-half-year-old Yinyin is ruthlessly abandoned by her biological father, the chancellor, just to make room for the true daughter. On the verge of death, she accidentally binds with the darling system! Thinking she would merely linger on in the cold palace, little did she know that the powerful backers she casually hugged were one stronger than the other: the haughty sixth prince steals imperial delicacies for her, the cunning third prince shields her from wind and rain, and the cold dark guard uses a blood-drinking treasured blade to pare apples for her! Not only that, even that tyrant emperor, feared by all, is melted by her! Watch how the abandoned little pitiful one successfully strikes back to become Da Chu's hardcore eldest princess, walking sideways through the inner harem!
