You know, instead of going the usual yuri harem slice of life plot line, wouldn't it be a much more fresh experience if this manga turn into a horror ?
Like, being trapped in a game world where everything is 0&1 and every route is predestined, where everyone you meet are no more than an NPC saying exactly what you expect them to say, and yet, the current route are wildly deviating right from the very start and you don't know how to fix it, or what kinda ends it would lead you to.
Personally, the moment the gal's response is verbatim to what she would have said to the boy is already terrifying..
Also, remember that this development (the gal stalking the her love interest, then snatching her away, forcefully, early in the morning) might be exactly the same as what she would do to the MC dude in the original route.
Well, i might be totally off the mark here, considering that it seems there is a LN source for this manga, but i gotta say what i wanna say. That kind of story would make your heart skip a beat, literally and figuratively.
