What do you mean by the ending from the stars? Don't know Korean?

Professor Du went to the wormhole because he thought it was useless to stay on his own planet for a long time. There, he found a way to return to earth. The first time he stayed 10 seconds, the second time was longer, and each time he came back, it was longer than the last time. So what Qian, Zhang and Li Zaijing saw was true. Do Min Joon stayed on the earth for the last time 1 year and 2 months. Although he doesn't know when it will disappear, he will try his best to come back every time! Finally, Du Minjun ended with "I'm back". 1 1 week, a total of 77 days, over! Hope to adopt! ! ! ! ?
