The female lead, Tong Tong, and the male lead, Shen Ke, had been married for many years. However, Shen Ke could never forget his late white moonlight, Sheng Zhi. By chance, Tong Tong saw a photo of Sheng Zhi that Shen Ke had cherished all the time. Only then did Tong Tong realize that the husband she deeply loved had always been in love with another woman. Tong Tong was completely disheartened. She lit the photo on fire, but unexpectedly, she returned to the day when Sheng Zhi was kidnapped seven years ago. Originally, she could have saved Sheng Zhi, but she gave up thinking she was in a dream. When she returned to seven years later, she saw the intact photo that had never been burned. A shiver ran down her spine. She guessed that she had traveled to a parallel universe.
