Dear Door Vol. 2

Kyungjoon is the Demon King Cain's door, and though he is still very much opposed to being used, he is slowly warming up to the surprisingly charming demon. Being Cain’s door has also put a large target on Kyungjoon’s back, and he now faces threats from both demons and humans alike. Worse, his best friend Jinyoung–consumed with jealousy over Cain–is about to do something that may cost their friendship, and possibly, Kyungjoon’s life!
