I remember the mc was a guy who’s family had to like feed humans to a snake god for protection. When he arrived at the place he didn’t actually get eaten and when he went to the door the snake god pretty much said “I don’t really eat humans anymore so..” the guy just ends up staying at the snake gods place for a while(the house is a abandoned mansion on a mountain). The snake god had dark skin and black hair, he was tall and could, of course, turn into a black snake whenever. I read this like two years ago so if you can help me find the name that would be great
