Everyone has their own unique life trajectory, because everyone's life trajectories may intersect but never overlap.
If you arrange your life experiences according to time, your life trajectory is a timeline. No one can tell how many things happened at a certain point in their own timeline.
At some point, you may regret so much that you want to go back to the past, to a certain point in time in the past, and start over from the beginning to make up for your mistakes.
One day, the protagonist of this book suddenly found himself strange! Yes! Very strange! She remembered that she was already 30 years old and was forced by her mother to go on blind dates every day. But now she found herself in the mirror wearing a red collar and white short-sleeves on her upper body and a red knee-length skirt on her lower body. Isn't this sailor-like dress her elementary school uniform? ! !
There is no doubt that the protagonist of this book thought of "travel" and "rebirth". She was at a loss and was secretly happy at the same time.
However, when she turned 30 again, she found that she had been made a joke by the gods. The past she returned to was only a time point in her own life. She can choose any time point within the 30 years she originally experienced to undergo infinite reincarnation, but she will never get out of her 30s.
She is trapped in her own time corridor!
