I didn’t think angels could feel pain.

Who said I was an angel.

Kim Jongin is bored of spending his time in Hell. He decides to take a quick trip upstairs to see what he can mess up in the human world.

There, he meets Kyungsoo, a naïve, wide-eyed goodie-goodie.

He can’t wait to mess up his life.

But Kyungsoo’s not exactly that easy to change and Jongin has to extend himself beyond all evil to turn things around.
