I'm glad I found this after it was finished. There are a lot of negative comments here.
Its a supernatural story, it could have gone any different ways, but did to keep the action and tension, especially with the ending ramping up.
I won't spoil anything but any ending is difficult to do. Resolution isn't just, and they had kids, happily ever after.
Now the whole story is here, give it a read. It would be great if the whole thing could be translated in color. But it would take a method to update existing chapters. My fav current Manga is haunted by an april fools joke upload that he can't have taken down.
But give it a read, its awkward sure, but for what it is, enjoy.
