I mean, I think it's a pretty common trope in shoujo/josei ("common" girl with an actor/singer/CEO/popular writer etc.), so if you browse those you'll find some. But I wouldn't expect most of them to be as chill as this one
My guess on the "godfinger" might be along the lines of "my finger was guided by the god and as such it was the god's finger that touched you" excuse, I think there was something like that in some movie/manga or something?
It seems they just added that credit page from the other stuff they upload, some kind of Naruto fanfic.
Also only two chapters seem to be done by them, while others were an MTL that has been removed in the time it took me to type out this response.
