In the late autumn of the 1980s, Li Xiaoyun was born in a third-tier town. This girl who entered school early and was always catching up has been accustomed to fixing the shortcomings of reality in fantasy since she was a child: the red cross on the test paper, the lag on the track, the whispers of adults. She didn't know that these "parallel versions" in her mind were quietly hatching an amazing ability.
At the age of 35, she discovered that she could actually fold time and space.
Starting from the junior high school classroom, she rewrote her life with a clear will: becoming a top student, admitted to Beijing's top medical school, and embarked on the path of neurosurgery - all just to make up for her deepest regret: to prevent her mother from being paralyzed and aphasic due to cerebral hemorrhage. She restrained her emotions, but was still hurt twice in love: her first love in college abandoned her because of reality, and her lover in the hospital betrayed and cheated on her.
It wasn't until her year of further study in Beijing that she met the man who was seven years older than her while the ginkgo trees were blooming in the Imperial College Street. There was freedom in his eyes that she had never seen before, and it also brought about the most difficult choice: to protect his paralyzed mother and a stable life, or to follow love into the unknown?
This is a story about "what if": if you could do it all over again, would you really be able to achieve perfection? In countless folds of time and space, Li Xiaoyun will eventually discover that true salvation does not lie in erasing all regrets, but in learning to coexist with regrets. When the coin flips in the air, with Scorpio and bow and arrow engraved on the front and back respectively, a ninth possibility is being born.
