Happiness Rides a Broomstick

Happiness Rides a Broomstick summary:

Although she is just a college freshman, Kim Danjo, much like her name, lives a monotonous life. One day Danjo goes to a storage room to run an errand for her sunbae when she witnesses a broom transform into a human girl. From that day on, the broom persistently asks for Danjo's help, claiming she has no where to go. In the end, Danjo accidentally gives the broom who claims to actually be a Dookkabei (Korean supernatural creature) the name Eundohae and they start living together in Danjo's small gosiwon.
