I don't mean that sercondary stories are bad at all, don't get me wrong. Especially in a game like yours which is, let's say, sandbox-like, it is good to add a lot to it. And yes, I know about that aspect of adding more details and info on the story, Kaede herself is evidence of it but my fear is stated above.
But I trust your script and I'm eager to know more about the story nonetheless.
