You were supposed to be a loyal follower of the church. That was what Kayden believed you to be. Until you were not, tempted by the devil, allured to the desires, you were gone from his grasp - and the natural reaction of getting angry, hating you, he could never do.

He already lost you once from the devil. Now, he has come back to retrieve you, to mend your sins into grace. He still wanted you to be safe with him, so he can't give up on you just yet.
