I didn't think much of it at first as I figured it'd be some sort of imitation of Kami-sama Hajimemashita, but I was pleasantly surprised with this one. ittedly, it's nothing that hasn't been done before, but it does have it's own charm.
It's pretty light hearted and some scenes had me chuckling out loud. Kagachi is adorkably pessimistic and insecure (and pretty much an idiot) and it's all played for laughs.
The main character is actually Kagachi, the good for nothing forgotten god, rather than Haru, but it does have a few aspects of a reverse harem, though it mostly seems to work as fuel for Kagachi's development as a character (he decides pretty early on and one-sidedly that she's his bride/wife/whatever and, as he's really insecure, he gets jealous really easily).
Haru is kind and lively and earnest, but not in an annoying way, but all in all she doesn't deviate that much from a typical shoujo heroine (at least she's not blushing 354 times per chapter, rather, he's the one doing the blushing).
But it's through Kagachi's eyes that the story is told and he's the one that grows the most. She's the one that helps him with that since it's his attachment to her that makes him want to change in the first place. He's also kinda perverted and I think it's pretty funny.
I'll give it an 8 because my expectations were so low, now It seems awesome in comparison haha.
It's not a masterpiece by any means, but if you don't have much to do, give it a go. It's really not bad.
