The overlap of parallel time and space, the confusion of time, and the invisible future.
Are you also counting the stars and looking at the moon, waiting for my arrival?
Lovers of parallel time and space, are you okay?
It means:
Song Zikang/Tong Rui, are you okay?
Or
I love you, you hear me?
Ps: An idea: Two time and space are tentatively determined. For some reason, Tong Rui traveled to the Earth where there was a bug or fell into a space-time rift and found this time and space. Song Zikang found this time and space, and asked him and himself to investigate the truth about his death in the laboratory explosion. During this period, a series of things that cannot be explained by science happened, which gradually brought the truth to the surface, but also involved the more complicated internal activities of the time and space detective. So the purpose of investigating the truth changed into a factional fight. What kind of secrets do Song Zikang and Tong Rui have?

Intention: Even if you can never see that person again, I believe that he/she will live well and well in another world.
