Billionaire Nathaniel Grant suffers from a fatal rare reverse-aging disease, with his life fading as he suppresses emotions. He accidentally finds blind masseuse Clara Sawyer’s tears can stabilize his condition. To survive, he forces Clara into a three-month marriage with her mother’s surgery fee, deliberately hurting her for life-saving tears.
Despite his schemes, they fall in love. Shattered by the truth that she is merely his "medicine", a heartbroken Clara leaves, pregnant. Tricked by his father into believing Clara and their daughter died, Nathaniel seizes back his family empire and lives in remorse for seven years.
The family reunites by chance. To redeem himself, Nathaniel abandons her tear treatment, undergoes a risky cure, and makes full amends. Finally, the pair embraces a hard-won happy ending with their daughter.
