The man always wants to talk. However, there is no clear listener. The only certainty is that he speaks while on the subway train. As usual, the man boards the Gyeongui Central Line that crosses the outskirts of Seoul, and without a specific listener, he starts recalling old memories and sharing stories about Mongolia in front of the train door’s glass. His words keep repeating or transforming, and while he does not know about the universe, he utters words as if monologuing about the principles of the Earth. His words, sometimes painful and wandering, flow out. At times, his face looks sad and forlorn.
