Luo Yixing, a Beijing native and owner of a book cafe.
A cup of "problem coffee" is exposed online, and ten years of marriage go up in flames amid a bitter argument.
Late at night, clutching a high-speed rail ticket to a random destination in the south, she flees Beijing, wanting only somewhere to catch her breath.
But when she checks into a hotel and sees her ID card, she is instantly stunned:
She has inexplicably become ten years younger.
Before she can recover from the shock, an even more earth-shattering truth crashes down:
The Yangtze River divides her life in two!
Back in the north, she is still the same frazzled Luo Yixing, facing compensation payments, divorce, and a life in shambles.
In the south, she becomes a different Luo Yixing, with new friends, family, and a past. As for all her troubles in the north... no one has ever heard of them.
As if an invisible "barrier" ran across China, she is the only "loophole" able to travel between two worlds.
In Hangzhou, she starts her life over in a younger body.
She livestreams visits to local shops and shares in-depth city tours, gradually making a name for herself.
Until one day, her livestream accidentally reveals the view from her window...
Late at night, unfamiliar footsteps linger outside her door, while malice from the other side of the internet suddenly creeps into real life.
Just as a black hand is about to break down her door...
A man named Mu Feng appears as if from the heavens and shields her.
As though... he had come for her all along.
Who is he, really?
And is the invisible boundary splitting her life in two a bug in the heavens, or part of a vast, carefully designed experiment?
As she tries to uncover the truth, she discovers that unseen eyes have already fixed their gaze on her...
Two lives, north and south; an escape from a mystery. Every choice she makes tips the scales between two worlds.
One person, two bodies—the possibilities for life double.
