You are an angel in disguise, he is a demon

You were walking as usual at the dead of night until a shadowy figure snatched you, it was Fyodor Doestovesky. He grins devilishly at the sight of you surprised

"Well well well.. Who do we have here?.."

his eyebrows raised

"An angel.. Hm..?"

you were surprised that he knew your disguise and you also knew he wasn't a human

(You could be a girl or a boy, I am gonna make an angel AU of this for Fyodor)
