The Cruel Prince

when i first heard that cardan was a faerie and jude was a human i was so confused because fairies are supposed to be really small and humans are big so i was like how would that relationship work out if he lives in a little house in a tree and she lives in a real house?? like i thought he would be the size of her pinkie and i didn't know how she managed to live in their world. like i literally imagined him living in an acorn house and her opening the door to see him and him sitting on her nose...
