After crashing to death with his motorcycle, Chanyeol becomes a lonely ghost who wanders the streets of Seoul. But when he visits his university cafe, he bumps into an acquaintance from his past life. Chanyeol, having nothing better do, follows the young man around everywhere. After being with him 24/7, although the other can't see or hear him, Chanyeol begins to realize he may not be the only lonely one.

You merely smiled, my world stopped.      Can he keep it and continue holding on it or will he let it go and wait for something better to enter his life?
