The emergence of the time machine was actually the beginning of the inventor's infinite nightmare.
His sister, whom he regarded as a treasure, died in an accident while hiking. The grief-stricken University of C physics professor Lu Xi used his identity as the developer of the time machine project "Final" to steal the time machine that had not yet been fully developed. Traveling through time, he thought he could save his sister, but he didn't expect that it would involve the life and death of another person... He wanted to save his sister, but he didn't want to harm anyone because of it. But in this reality where we cannot have the best of both worlds, after trying again and again and failing again and again, no one knows whether Lu Xi has already lost herself.
In this never-ending despair, too many causes and effects accumulate, and it becomes fate.
He couldn't forget the words she said with a smile under the bloody sunset——
"I want to find you in the future."
