Lin Shuyao, the daughter of the Lin Group, has lived in a carefully constructed "perfect world" since childhood - her family is a benchmark in the business world, her father Lin Zhenghong is a philanthropist, her stepmother Su Wan is gentle and considerate, and the family's old house is a top landmark in the city. Until her 22nd birthday, she unexpectedly found an encrypted diary and half a yellowed old photo in her grandfather's dusty study. In the photo, in addition to her young grandfather, there was also a strange woman and baby. On the back was a line of vague words: "1998.7. Unfulfilled promise." This discovery, like a pebble thrown into a calm lake, revealed the secrets that had been hidden under the Lin family's glamorous appearance for more than 20 years.
