I'm kinda upset we'll probably never see her again, and this feeling will probably repeat several times before the end because there are gonna be other girls I find adorable who I will probably never see again until the eventual delivery room/nursery scenes at the very goddamned end of the manga.
@Darcow gotta save something for the doujinshi spinoff lol. Sleep sex is a pretty uncommon niche to take advandate of (no pun intended).
@tehcoopatroopa it is only ch. 3. Seems like it's gonna be a revoking door but I'd be surprised if the other girls didn't at least make some cameos here and there in the future.
