My Wife Breaks the Plot

A woman finds herself transported into a tragic novel as the original female lead, destined to be used by the male lead for her sister's blood transfusion. Refusing to follow the plot, she beats up the male lead, sends the supporting character to a mental hospital, uses system rewards to counter poisoning conspiracies, and exploits a bug to bend time and prolong her life. Ultimately, she exposes the truth, makes the male lead chase her to the crematorium, and donates his property to charity. When her mission is complete, she returns to reality with her dog, leaving him alone.
