A wealthy heir elopes for love and enters an underground racing competition to help his beloved open a shop, only to suffer a serious car accident. To save him, the heroine tearfully aborts their child and donates one of her kidneys to him. Under pressure from his powerful father, she is forced to leave. Misunderstanding her departure as rejection, the man is consumed by resentment. Five years later, now a powerful CEO, he runs into her again at a hospital—only to find her living in dire straits, with a cowardly husband and a son suffering from heart disease. Unwilling to let go, he begins to close in, making things difficult for her, unaware that his actions nearly cost the life of his own son.
