Its not drawn "badly". It is meant to not be aesthetically pleasing in typical way. But It is not "poorly drawn" because mangaka puts in a lot fo effort into panels and atmosphere they create. So it is drawn to look "messy" and creepy for horror factor.
So hear me out ... I know this is gonna sound hella weird but this is the only way I can see a happy ending for the people who matter ... Reiji should marry the teacher and they should adopt Nagi.
I know it'll be weird especially since Reiji's slept with both of them but it seems that both Nagi and Sensei want a family (in a way Reiji too as long as its "normal"); Nagi doesn't seem to care about her role in that family as long as she has a loving one and Sensei wants to be Reiji's wife. Sensei also wants to take care of Nagi to fill her "caring/loving role" and to secure her position as wife with Reiji. If they all come to an agreement and leave that town together I think it can work out in a weird way. Not sure about Chako though but it is what it is ...
The whole love triangle-pentagon- polygon shape drama is starting to get on my nerves...
I swear if author tries to pull a cheating-misunderstanding-"look at me too" arc while they are dating I'm dropping this.
I hope the writers make it make sense.
