The inner house of an ancient wealthy family is used as a chessboard, and the sinister human heart is used as a chess piece. The good-for-nothing heroine, who is an ant at the mercy of others, wakes up in a desperate situation due to a fatal frame-up. She uses her mind-reading skills to gain insight into the hypocrisy of the world. From surviving with endurance to counterattack in a dark way, she tears her enemies apart and takes everything back, interpreting the core of the feeling of "survive a desperate situation, break the situation with your heart, good and evil will eventually be rewarded".
