One light-year is 9.46 Trillion kilometers, and the number of light-years from one end of the universe to the other is countless. This is enough to call it a vast distance, but I will never need any time to reach it and find you.

PS: The background of the universe era does not involve war, it is just a story of two people falling in love~~
