The Doctor Is Reborn to Make up for His Regrets

In 2024, Lu Shichen, a top expert in cardiac surgery, died suddenly on the operating table. When he woke up, he found that he was back in 2009 - the summer when he was eighteen and the college entrance examination ended. In his previous life, he was a genius in the medical field, but because he was obsessed with mastering a surgical technique, he missed the woman he loved most in his life, Su Nian. She waited for him for twelve years, from adolescence to thirty years old, and finally married someone else and died in depression. And Lu Shichen didn't know that she had never stopped loving him until he saw the letter she left for him at her funeral. After his rebirth, Lu Shichen had only one thought: In this life, I will not be a god at the pinnacle of medicine, I will only be Su Nian's husband. But he soon discovered that fate had given him a chance to come back, but had set a more cruel test - Su Nian's congenital heart disease deteriorated faster than he remembered. She may only have three years left to live.
