When she regained consciousness, she had become a strange girl - Lin Sang.
Memory is like a shattered mirror, with only sporadic fragments left. She can only rely on instinct to explore the world and gradually adapt to the identity of "Lin Sang". When she got along with friends in this world (who also looked like her in the original world), her memory became clearer and her desire to go home became stronger and stronger, until she accidentally learned about a mysterious organization - the Eye of Time... As she gradually investigated, the truth gradually emerged. It turned out that her arrival was caused by herself. A tragedy. She is a genius who cannot understand or accept separation. With her super high IQ, she breaks the order of time and space and comes to this world with a slower timeline. The butterfly effect makes this world subtly different from the original world: the tragedy that should have happened is rewritten, the people who have passed away are still alive, and all tragedies are slowly saved...
