Yoo Joonghyuk was a good priest, one who had never given in to any sort of temptations. He lived for his duties.

However, recently, a certain very annoying succubus had been tormenting him, making his life impossible. Every day he tried to avoid him, and every night he prayed for his life. The being called himself Kim Dokja and had a special liking to randomly appearing in his room at night, whispering unspeakable things in his ear and giving him dreams he didn't dare to describe.
