There is a kind of person in the world who is as simple as a symbol. No matter how many words you record, you still can't fill that image. Maybe one day the person you pass by will be him. You can only hope for this baseless feeling of bond between two people. If not, then this person really did not exist.
I once naively thought that I stayed with that person just for the so-called 'way home'. But at the moment when time and space alternated, I suddenly longed to return to him, to a world where even though he had disappeared, there were still memories to be found. However, the mistake of turning around caused a difference of thousands of years. So, I can never see him again...
