Shen Moshu, an ancient book restorer, read out her past life in a century-old diary - she and time physicist Lin Shixu fell in love repeatedly and sacrificed for each other in three parallel timelines: the revolution of the Republic of China, the campus in the 1990s, and the contemporary city. When quantum entangled memories leak out in reality, they must choose between "erasing their loved ones" and "forgetting themselves", only to finally discover that in the folds of time, only love is the eternal anchor.
Purpose: Using quantum entanglement and time folds as metaphors, explore the nature of love in the cycle of destiny - true love is not an obsession with the past, but the courage to write the future with your lover on the blank page of time.
