(Male) Naga x reader

Nasthair. The one everyone in town is afraid of. The one who killed thousands without mercy. The one who is half snake and half man, Naga. No one knows his full name. All that is known is that whoever enters its soil will not return alive. And if they does, then not healthy.
He's a very selfish and evil creature.. That is, until Y/N comes along. How could a 'little girl' like her walk away from Naga alive and well? What the hell's going to happen between them?
