While age of consent differs from country to country, we pretty much all can agree that a teacher hitting on someone in high school isn't very good. Also, considering that the MC is 18 and it was said it was going for a few years which isn't very good. And, in the case where 'morals/ethics get tossed out the window' doesn't happen in many of the visual novels I've played, only this one. And it just doesn't settle right with me. If you've played a game where stuff like this happening with minors by a legal adult then maybe you should question the developer. I am also aware the age of consent in Japan (where I believe this takes place, correct me if I'm wrong) is 13, it still doesn't really make it right from a world viewpoint. 13 is young. Too young. I don't really know what I'm saying right now, sorry if this is hard to read or make sense of, I kinda jump between topics a lot and I'm sorry. Anyway, have a great day!
Also, your note about Dozer - EA is a great game, but I can't see why you make that comment. He is actually a sweet heart.
