... I mean, I don't really have anything to add. I already said my piece on the 2.1 part. This is just a continuation of waiting until something more substantial happens. Or more seggs.

I mean, pregnancy doesn't happen usually in normal Manga even if it's considered as borderline.
Heck even in Hentai's, pregnancy only occurs at the mid or end of the story, not immediately at the beginning.
There are even series which outright remove mention of impregnation in their Manga adaptation, even though the source Web Novel has it.
