I can't believe I have to explain the concept of a VN, but, here we are.
That is NOT what a VN is about. The VN concept is about a STORY, where all the characters exist. Like a Book. Yes, there can be paths and routes, and favorites and everything, but all that MUST exist within a cohesive STORY. Not in a sequence of stories.
If the waiting for that specific girl is bad for you, you are obviously in the wrong game, or, the VN isn't really interesting. Because in a VN, the whole story is meant to be relevant, not only some parts. That's for Sandbox. And NO, a sandbox is NEVER about a Story, is always about breaking the story in pieces, like ripping chapters of a book.
So, when it comes for a good story, a VN model is unbeatable, and when it comes to breaking the story into unrecognizable pieces that don't share anything at all with each other, sandbox is the thing. What you are trying to get, is a sandbox experience in a VN, and that, will never be good.
Abandoning the story to dedicate to single paths, because they are after all easier to write in the time constraints this Dev imposed to himself, is a really bad idea, it kills a good story, in order to have a lot of small stories with no interest whatsoever. Because what made this worth reading, was the navigation between the characters, the interactions and so on. Now, after this, there's nothing but endless sex scenes with this or that one, and then choosing another one, and so on. It completely destroys the story.
It is indeed a sad thing.
