Zhou Yuan's world before the age of thirty was a boring step-by-step script: work-eat-rest, day after day.
Until three hourglasses gave her the ability to reverse time, she was surprised to find that there was no girl Su Nian in her future.

Zhou Yuan began to travel through time and space again and again, investigating between reality and the past, trying to Unraveling the fog of death, however, each step back brings her closer to Su Nian. She desperately investigates in reality and blocks time, only to find that Su Nian's life is far more complicated than it seems. Under the fog of death, there seems to be a bigger secret hidden.

Will they meet in countless parallel time and space futures?
