Ten years after the male lead's death, the female lead was devastated. Because of her position, she had studied medicine, but not to the point where she could perform surgery. After watching her lover die, she slowly rose through the ranks, only to discover that she had developed problems such as trembling hands, and eventually gave up.
Then one day, a System suddenly appeared and said it could bring the male lead back to life. But there was a condition: he would fall in love with someone else, forget her, and have no past with her.
The female lead was in terrible pain, but she was also thinking of the male lead's well-being. She asked whether he would return in good health and whether he would suffer any pain. The System said he wouldn't. Later, the male lead returned, and eventually he and the female lead met again. He didn't recognize her, and more heartbreak followed.
Later on, the male lead had a woman by his side, but kept his distance from her. He was still the same as before. What's more, when the female lead brought him back to life, she felt that he hadn't changed at all. It took her two months to realize the truth. And the male lead didn't simply appear out of thin air. Later, when there was a second car accident, it turned out that the male lead had been trying to save the female lead. He confessed to her that he knew about the System and had acted that way to avoid it. In truth, he had always loved her deeply, which made her suffer even more.
When he was rushed into the operating room, the female lead was determined not to let what happened during the first car accident happen again, when she had failed to save the person she loved. She resolutely stepped back onto the operating table.
