Daemawangipnida, Seolgeoji Haedeurilkkayo?

Abel, the Demon King, suddenly appeared at the house of job-hunting student Kang Woo-ri! This great demon king has a knack for housework, and he'll do all kinds of household chores if you're willing to give your soul as payment.

“Can I get a job?"
Just sell your soul!
All of your life's annoyances will be solved!

But the Great Demon King isn't the only one who suddenly appears... There is a "ghost" that pops up anywhere at any time! And there's that ex-boyfriend Hyunseong who broke up a few years ago? An urban fantasy romance that's often slapstick, usually playful, and sometimes even serious!
