I just hope this doesn't turn into a harem. i'm kinda tired of them

Does this series have any romance in it? like eventually becoming a real couple or something.

Yes, thanks a lot.
I've been looking for a long time but couldn't find it.

I'm looking for something about a witch in a forest who can't leave her house(?), and a girl who finds her and starts living with her. Sorry I can't remember much, I found it a while ago but i think there was also a village nearby that was plagued near the end or something like that and the witch and girl died together(eternal sleep?).
