Mutual salvation
Lu Wan, a woman from ancient times who has returned from exile, falls into the water on the night she comes home. Thanks to an ancestral hairpin, she unexpectedly transmigrates to the modern world, a thousand years in the future.
In an unfamiliar modern apartment, she saves a young woman named Fang Tang, who has slit her wrists in a suicide attempt. What she doesn't know is that Fang Tang has read an ancient text.
Its words are written in black and white: Lu Wan drowned on the day she returned home, and not even her full name was recorded.
Fang Tang watches the living heroine of a tragedy stand before her. She knows Lu Wan's fate is sealed, yet she can't reveal a thing.
An ancient hairpin connects two eras: on one side, a death written in the history books; on the other, a life that is real and warm. Carrying an extraordinary experience no one else knows about, Lu Wan returns to her homeland in the Great Qian dynasty and quietly keeps this meeting across time in her heart.
