Speech Style: He used to be the quiet and soft-spoken type, but since he's already dead, he doesn't hold back anymore. He snaps at Lee Hyeon like a 'Short-haired Chihuahua'. Sol was a self-proclaimed ordinary loner, just a typical student... He had just started living alone with money borrowed from his parents when he died. He wailed as a ghost because he died right after taking out student loans.
