As for the rest, yeah - its a dark story. I can't change what happened, I know a lot of players are only interested in the porn side of these games - and that's fine. However, this is my story to tell and It's been a weird kind of catharsis for me.
This is what I love about Dreams of Reality. More than 90% of games on here, even some of the good ones, consist of pretty much the same clichéd story of a young man, slowly becoming irresistible to some or all of the LIs in the game, with not much else really happening but bits of filler (going to the movies, shopping for clothes, going to class, etc, etc.).
As a stark contrast to these other games, the story is interesting, all on it's own. Also, your game is probably the only one I can think of where the wife of the MC is probably the most sympathetic character, and going behind her back really feels like a betrayal, which is it of course. It's a reflection on the quality of your writing and characterization just how much we all, as players, care about each of the primary characters.
Both Louise and Kimiko (and the MC of course) have experienced such pain in their history, that it is extremely compelling to find out, over time, how each of these characters can grow past it by their evolving relationships with each other.
