Born with a serious heart and lung condition and treated as a burden by his own family, Elias signs a care contract with Sebastian, the cold and powerful heir to a wealthy empire, simply for a chance to survive.
At first, Sebastian sees Elias as nothing more than an old debt he is obligated to repay. But through repeated abductions, public humiliation, and ruthless family schemes, obligation turns into fierce devotion. Sebastian begins defying his family, the board, and even death itself to keep Elias safe.
Meanwhile, Elias refuses to remain the fragile young man everyone expects him to be. He fights to reclaim his inheritance, reopen his gallery, and establish a medical foundation for others who were once abandoned like him.
When the contract between them is finally reduced to ashes, they realize the truth: what binds them was never charity, possession, or a temporary arrangement. It is the promise of two lonely souls choosing each other—and choosing to stay alive together.
