Dan-Jo is a freshman in a university and lives a monotonous life. On orientation day she goes to the warehouse on an errand for her senior and witnesses a broom that transforms into a human. From that day on, the Broom Ghost persistently asks for help from Dan-Jo, who she has never met, saying she has nowhere to go. In the end, Dan-Jo accidentally gives the Broom Ghost, the name 'Eundohae', and they live together in a small gosiwon. In return the Broom Ghost promises to make Danjo happy.
