Shen Yao has lived for twenty-six years and has always known that she is a substitute - she looks like Ji Xiao's dead first love. She was raised by the Ji family and became the quietest shadow next to that man. She is obedient, gentle, sensible, and never asks for more. Until one day, she discovered that she could "travel" into the objects around her while she was in a coma and see the truth that those objects had witnessed. In an old watch, she saw her stepfather's strange smile after her mother's funeral; in a discarded mobile phone, she recorded the words "You are different from her" that Ji Xiao said to her sleeping face alone late at night. When her stepfather's conspiracy gradually came to light, and Ji Xiao's "protection" was far deeper and longer than she imagined, Shen Yao finally understood that she was never a substitute, but his weakness that he had carefully hidden for ten years.
