To experience a sweet-pet plot, the heroine enters a book and accidentally transmigrates into the early-dying vicious supporting character Su Ruan. Right at the start, she smashes the head of Yan Chen, the crazy villain of the entire book, forging a mortal feud. Bound to a deadbeat customer service, she embarks on a survival mission to protect her life, rewriting the original character's self-destruction plot and neutralizing the heroine's murderous intent. Unexpectedly captured by Yan Chen, she is poisoned and controlled by him. Amidst tug-of-war probing, suspicion, and strategic gaming, the crazy villain and the cannon-fodder supporting actress unfold an extreme push-and-pull redemption romance.
