Shan Ran discovered that she actually had two hearts. What was even more suspicious was that she could hear other people's inner voices, and all of this happened after an accident...
After the earth exploded, the survivors moved to a planet called Kotal, and the human laboratory invented a time machine. Shan Ran went back to the past, and she wanted to understand why she had two hearts, and she also wanted to find a way to save the earth or save more people.
The principle of the time machine is to allow those cosmic particles from the past to coincide with us now in a certain space to form a new old world. But this process is short-lived, and space may explode at any time.
The world is still the same as in Shan Ran's memory, but a man breaks into her life and changes everything...
