On their twenty-fifth wedding anniversary, Vivian Hurst received two life-altering gifts. One was a medical diagnosis from her doctor: “Late-stage pancreatic cancer. Two months left, at most.” The other was from her husband, Sylvester: an invitation to his mistress's lavish beachside birthday party in Miami. For twenty-five years, Vivian had been the perfect, dutiful wife, enduring his coldness, his emotional absence, and his endless devotion to another woman. Broken and exhausted, she left a divorce paper, choosing to end her agonizing "lesson" of a marriage beneath the dark ocean waves. But when Vivian’s lifeless body was recovered, the devastating truth shattered Sylvester’s world. Paralyzed by profound regret and boundless grief, Sylvester wept until his heart broke—only to open his eyes and find himself thrown fifteen years back into the past. It is May 20, 2018. Vivian is still alive, and her cancer hasn't taken her yet. This time, the arrogant billionaire vows to tear up his contracts, burn down his old life, and spend every heartbeat begging for her forgiveness. But can a shattered soul truly learn how to love before the clock runs out?
