A pretty enjoyable YA fiction if that's your sort of thing. Art, worldbuilding, writing and character dynamic are all pretty well done.
My two biggest issues with this vn are:
1. Sex scene isn’t the best way to begin your story. It may lead your protagonist to be perceived as a horny nymphomaniac who’s main goal is getting laid, and while I know that’s the reason why a lot of people read fvn’s in the first place, it never the less can create a negative first impression, so that’s probably something you should not disclose about protagonist’s character for quite while.
2. I don’t like Calbex. As far as I understand knight’s duty aside from fighting is to be a good mentor to their squire yet Calbex has been neglecting both of these duties just because he is on recovery… apparently. Corwan works is ass off to become a knight yet Calbex simply doesn’t care about him or how well he becomes one, leaving his mentorhip to everyone else. He doesn't provide any mentorship, any guidance on what’s knight job is, doesn’t take any effort to encourage or discourage his passions… hell, he doesn’t provide much of an attention to hm really. I guess it’s for setting up his character arc but, like, doesn’t even higher ups demand of him to provide at least some sort of mentorship while he is recovering from injury? How is he still not in a retirement and out of the job? At this point I won’t mind if Corwan would be assigned even to Fen. Like sure, he is an ass, but at least he cares about rising good squires. Calbex, on the other hand just doesn’t.
