Man, ChatGPT is pretty good at this, huh? Nice to see a fairly readable version of the game in English - Evenicle 1, this, and Oyako Rankan were some of the first games I ever read in Japanese when I was a beginner (and it was very slow going), so it's cool to see the game become accessible to more people. Alicesoft has always utilized NTR in what I feel is the best and most interesting way - as a fail state, or as a result of the player screwing up. Of course, this also means more effort on the side of the devs, but the end result is a game that appeals to both audiences.
I'd add Haha Ranman to your list of games, personally. It's the most recent full game in their MILF line of games, and while it does away with the NTR, it has the hottest scenes Alicesoft has ever created, and some of the better writing.
