"I traveled through a hundred years just to prove that I was once loved."
The 28-year-old ancient books editor has a lingering sense of alienation between his eyebrows. The death of her grandmother and the mysterious relic dragged her into a time and space mystery that began in 1937.
Holding seven unopened letters in her hand, she stepped into the rainy night of Jinling in the Republic of China on a full moon night. There is a man there who always forgets her - Shen Qingrang. Every time she travels through time, she gets to know her again, and every time she separates, her traces in the modern world are erased bit by bit: photos are missing, relatives are forgotten, and work records are blank. She is struggling between two time and space, while pursuing a doomed love in the flames of war, while fighting against the demise of her own existence in reality.
In the end, she discovered that the deepest time paradox is not to change history, but that she is history itself. The grandmother who raised her is her old self who returns from the future. The answer she has been searching for all her life has already been written at the beginning of her destiny.
A searcher for love lost in time and space, a witness walking the tightrope between existence and nothingness. Her journey is not to save love, but to learn how to live with eternal loss and salvage from it eternal evidence of love.
