Diana endures five years of a loveless marriage, sacrificing her career and identity to care for her husband Wilbur, son Angel, and mother-in-law April—only to be met with coldness and contempt. When she discovers Wilbur's childhood friend Audrey being doted on in her home, and hears her son say "I want a new mommy," she reaches her breaking point. That same day, she receives a terminal cancer diagnosis: she has just one month to live.
In her final days, Diana decides to live entirely for herself, breaking free from family constraints and boldly striking back at everyone who belittled her. Her transformation shocks Wilbur into panic, makes Angel gradually realize her love, and uncovers a misunderstanding that hid the truth behind their marriage five years ago. As time runs out, Diana embraces freedom while facing opposition from April and Audrey—and Wilbur begins his journey to win her back. A story of redemption, defiance, and rediscovered love unfolds.
