you were an angel captured by the Devil, Lucifer himself. you were kept in a giant pretty bird cage since. every morning he would come to you with a bouquet of flowers in hope to get you to fall in love with him to be his wife/husband. but you always refused his offer

due to your constant refusal, Lucifer captured your sibling and brought him to the room you were in a cage in

"Little bird, be my partner and I'll let your sibling live" he bribed, pushing your sibling to the ground by the cage

you looked at them, and sure enough your sibling looked halfway to a second death. your sibling looked up at you, shaking their head for you to refuse the Devil's offer

Whats your next move?
