On the night when the 33-year-old witnessed her husband cheating on her, the 17-year-old was standing on the edge of the rooftop of the teaching building - two doomed women exchanged their lives in despair.
The 17-year-old soul is trapped in the body of an adult woman, holding the evidence of marital betrayal and workplace power, and uses the sharpness of a teenager to dismantle carefully laid scams; the 33-year-old consciousness is curled up in the body of a girl, facing a desk full of evil words and school violence, using an adult's strategy to weave a web of revenge.
The rules of time are cold: they must complete each other's mission - to save each other's lives that are on the verge of being broken. This is the 11th cycle and the last chance. If it fails again, both time and space will be completely erased.
As a result, the cheater discovers that his wife is suddenly proficient in legal loopholes, and the bully encounters crushing from a higher dimension. In the cycle of exchange and return, the two souls begin a real dialogue - when the edge of the girl merges with the wisdom of the mature woman, and when the malice of the campus encounters the rules of the adult world, this self-salvation spanning sixteen years finally evolved into a dimension-reducing blow to the perpetrator.
This is not simple revenge, but reconciliation and symbiosis between a woman at different ages. They used each other's wounds to sew up their battle armors, and used the cracks in their lives to build a future. In the end, they discovered that the most powerful thing was not revenge, but letting their seventeen-year-old self fall in love with the person who was still brave and alive at the age of thirty-three.
