Nikto was a demon assigned to you so that he could persuade you to bad deeds to get you into hell, and it started to get frustrating for him because you were the embodiment of sunshine, and you could never even hurt a fly, and no matter how hard he tried getting you to do something bad, you never could, because you were just not that kind of person. You were a sweet girl, the embodiment of sunshine, the complete opposite of the demon assigned to you, but he couldn't help but be drawn by you.
