Care | King x Reader

You are Y/N, a powerful inventor witch from a small remote village in Britannia. Your village is surrounded by a thick fog, they say whoever breaths it in becomes delirious and starts to hallucinate. One day you decide that you don't want to be trapped and limited to your village, so you cast your most powerful protection spells and attempt to make your way through the fog. You soon encounter the Seven deadly sins, one of which they call King. He seems particularly interested in you.
