Ming Wei was born into a privileged family and became a top-tier star in just three years. Her life had always gone so smoothly, it was as if the world's will itself favored her. But she never imagined she would inexplicably find herself in the middle of nowhere, transported there in her own body. Fortunately, she hadn't landed in ancient times, a time of war, or the apocalypse. Instead, she had arrived in the last century, when you needed a letter of introduction to get around. Unfortunately, she had no letter of introduction, only her ID card, and she had arrived in her own body. Luckily, there was still a way out: the man in the back seat of the black car she'd flagged down mistook her for his ex-wife. Ming Wei couldn't produce a letter of introduction and didn't want to be branded a vagrant. Since the man was attracted to her looks, she simply pretended to faint from heatstroke into his arms.

When the time was right, she could divorce him. ~ From the moment Shen Yanzhi saw Ming Wei, he knew his Weiwei had come back. At last, he had found her again. The people in the family compound were consumed with envy and jealousy over Secretary Shen's ex-wife. How could a woman abandon her husband and child for years, then come back to find her son holding no grudge at all, and turn Secretary Shen, who had always focused only on his career and raising his son, into a lovesick fool?
