I downloaded the Taboo Edition, and oh boy, there's not a single Land Lady or Roommate anywhere in the story!

If you're offended by inc**t, this is not the game for you. Because your Mom is your Mom, who's hiding an intriguing secret. Your sisters are your sisters. And everyone is a possible love interest, especially if your choices put you on the Harem route. 

I enjoyed the heck out of this game, found the storyline original, and really appreciated the ending.  Definitely looking forward to more games from this developer!
