So, some key points here:
-The 'lectures in love' skit was a fair bit of fun. The game is obviously inspired by LIL, and some tongue-in-cheek parody was a good play on things.
-It may just be my screen but there were times when the dialogue text went below the visible screen. Eg: when Shiori says "Yes, but I thought you were one of those odd, degenerate teachers with no intellect whatsoever who only happened to get this job by sheer luck and are only in it to be around high, and then I presume she says (school girls), but that's below the visible area.
-There are also some cut off words or oddly inserted letters in the same scene. Eg: "Well, I have been curious about how stories will be like with art to go along with c "
-With Izumi, some people will REALLY not like her having a boyfriend. This is not a complaint, but just asomething the developer should be prepared for.
I see it's listed 'part 1', so presumably 'part 2' will complete this part, but for now... it's okay for an update. There's not much NSFW, and it a bit of character building/plot developments. Which is fine for a LIL-like game, but for the amount of time between updates I'd expect a bit more content. Perhaps Part 2 will solve that though.
