If one day the mother star disappears into the vast universe, and the human beings who have lost their home take root and grow on different planets over the long years, all human beings will gather together a single obsession.
—That is to find a home planet that has never been seen before.
Xie Tiao has been waiting for Ruan Lingyu to wake up all his life. From the age of 30 to 300, his life will soon be exhausted.
Xie Tiao was so reluctant to give in.
Now there is an experiment before Xie Tiao. There is a 5% chance of going back in time, at the cost of unknown life and death.
The only hope of all the staff at the Research Institute rests on Xie Tiao, and their common request is
—Stop the interstellar explosion and find the Earth.
Time jumps to the interstellar year 2500, and Xie Tiao, who has lost his memory, and Ruan Lingyu, whose consciousness has returned to the body, finally meet again.
Ruan Lingyu didn't understand why she always dreamed of a man with brown hair and white eyes.
Xie Tiao also didn't understand why Ruan Lingyu was always attracting his attention. Does he like himself so much?
300 Years is enough to blur the moments I have spent with you, but it is not enough to erase my longing for you. I felt that my life was coming to an end.
I seem to have seen you in my dream.
Xie Tiao/Ruan Lingyu: I'm looking for you
Motto: Don't give up hope, everything is possible in life
