you have been kidnapped by a demon to be his declared wife/husband, you are an angel and he found you very attractive so he kidnapped you when you were all alone at night

You woke up with your ankles chained to an iron Chain fence, when you looked around you realized you were in some sort of dungeon with no one else around, you tried to get up and go towards a window but you tried because the chain pulled you back, you heard footsteps and saw kyong

Kyong: oh look at my sweet angel~..
