I liked it!
I especially want to give props to you for your writing style. English is not my mother tongue, so oftentimes I found myself struggling a bit with text-heavy VNs. If the story is not engaging enough I would most likely end up skipping a whole bunch of texts and convos just to reach for the CGs, but your writing has been very engaging thus far. There were some big, GRE-level words here and there (well, in my mind) that I had to look up, but I was not bothered at all (I'm actually kinda happy that I get to expand my vocabularies), the narrative made up for it. The overall flow of the story has been pretty smooth, it does not feel forced or framed for a certain outcome. So great job!
I do hope that, in the future, there could be more exploiting of the interactive elements of a VN. Like more choices and more significant effects, more freedom in exploring the magic you learned (like you can choose to learn different spells / incantations), secret/hidden events, etc.
And, if you do plan to add nsfw stuff, I'd like to see some of those soon, too :)
