Hi, reading a comment gave me an idea that could greatly improve the game. I think you should add, from the beginning, the option for you, as the player (husband), to accept or refuse Hana's sexual advances towards Yuma. You should be able to decide that they don't do anything behind your back and that he doesn't just remain a spectator at the end of the game. Obviously, I know that's what excites the husband the most, but it would be great if you, as the player, could change that based on the decisions you make throughout the story. I'm not saying there shouldn't be any "training" for Yuma, because a game for a normal couple wouldn't make sense, but you, as the player, should be able to decide how much that "training" progresses and whether the husband has more sex with Hana throughout the game. I know it would be difficult because it would practically be two games in one, but it would be a great addition.
