Not a bad read! Though there's apparently more to come, I feel like the story works pretty well as a vignette even now. Many worldbuilding details will presumably be fleshed out and paid off in what is set to follow, but other plot points – like the protagonist's sick mother, or his academic exploits – do come off as interesting context for the characters and the drama between them. It's honest slice-of-life but well enough paced and structured to avoid the worst pitfalls of the genre.
On the other hand, I feel like the prose could use some further polishing; many lines feel kind of clunky and labored. At the risk of getting too nitpicky, let me pull out an example of what I'm talking about: "Finally passing through the gate, I try and estimate the amount of time I have left before my first lectures at the academy begin." First of all, I think "try and estimate" sounds less natural than the more obvious choice "try to estimate", and "the amount of time" is sort of a heavy phrase – "how much time" or some other rewording would probably work better.
Also, for a narrative that feels like it wants to evoke a strong sense of setting, I think it doesn't really push the descriptions far enough. Though the writing pulls off the mechanical delivery of information, the sensory experience of what it feels like to live in this world is not painted sharply enough to really elevate the worldbuilding. The tangible physicality of the character interactions is good, however; it feels like the game pays attention to all the correct things there.
But even if the presentation is not without its issues – the sprites jumping around as a result of some expressions being misaligned, for instance – I would call the art the VN's strongest aspect overall. There's a lot of it (the opening sequence is so charming!), and it's erotic in a sort of classically romantic way that fits the relatively restrained story. Though there is some rougher and less refined stuff in there, it feels like nailing expressions and anatomy was a priority, and it works out fantastically. It's just pleasant to look at all around.
