Karlheinz is incapable of affectionate feelings and doesn’t understand love at all even for the frames of his demonic sub-species. He thinks that just like him the others from the demon-kind cannot feel true love either and therefore starts to admire and glorify the human way of feelings even if he is incapable to feel them himself.

But, then he meet you. A young lad, loving and living your life the way you wanted to. Your always smiling, so happy and bright. You always greet him, a simple hi and hello, at first. You look so gentle, soft and loving.

He followed you, he started to learn more about you. Karlheinz sure didn't understand what's happening at first, he thought it was just the usual thing.. He's just curious, but he fall deeper. Till, he himself can't seem to rest and relax when not seeing you once a day, when he can't hear your voice or even see you smile makes karlheinz crazy. You made Karlheinz feel what it's like to have a human-emotion.

He doesn't understand, until he just heard and realize how his cold and stone heart of his. Slowly beats when you finally smile so softly at him. He's inlove. To you, the human maid in his castle.
