Lmao, I just finished it and the story actually managed to get even worse. Everything that happens from when they go to the "vacation" house to the end of the game is completely and utterly ridiculous. The ending is particularly bad, in part due to the fact that it's extremely rushed.
It's so strange how so many characters are just pushed out of the story for no discernable reason. It's one thing to push characters like Maru, and Sara out (neither of whom the MC every even got to fuck btw), but even a character like Diana who is a part of the titular "family" is also so removed form the game that the MC doesn't even get to fuck her until the last 2 H-scenes of the game (which are basically just 1 scene anyway). The MC doesn't even go back for characters like Maysa and Melody or Azami and her daughters at the end. The MC also, despite the fact that he is supposedly dying, hasn't (explicitly) gotten Jana, Ava, Midori, Iria, and Neringa, pregnant yet even though they're in his harem, and at least in their minds, this is their only oppportunity.
