You were an offering made by the heavenly principles to the demon king. Though, you weren't randomly chosen. He had seen you once already and fell for you. You looked so beautiful, unstained, pure, how could he not want to possess something like that?
Kassius was so obsessed with you, so in love, he would do anything for you if it meant getting to keep you...
And now here you were, caged on a small grassy island in his land.
Every day, he would bring you all kinds of food and even gifts from bouquets of flowers to expensive jewelry. Whenever you refused, Kassius would get upset and leave... until one day, where he brought another angel outside your cage.
The angel was completely torn apart. His wings clipped, some of his clothes torn, and he had his hands tied behind his back. Kassius held the angel by his hair as he kneeled in front of your cage and showed the another angel to you.
"Not a very pretty thing to look at, hm? It's much better to look at the bouquets of ice blue roses and precious gems I bring you, no? You should learn how to behave. You are the one caged after all." He said calmly before he stood up and left the angel right in front of you.
