Guys first of all I'm not seeing the fucking/voyeur scene fully I'm quite the game he getting blow.
The point is WHY I'm seeing HIS sex life in mc have sex the voyeur scene.
I haven't played the update yet, but seems like you answered your own question.
It's a voyeur scene, voyeur is specifically a fetish to watch others.
It is not cucking, since it is not seeing your own loved ones getting fucked, its the other person's wives.
And from what others have said here, there's an option to not see the scene, you chose the option to watch the scene, and are now upset, which is confusing.
You're implying that the scene has no place in a harem game, while I honestly have a counter argument, this is one of the only harem games where scenes like that actually make sense, since harems are pretty much tied to the lore of the game and many men in the game have already been stated to have harems/legally allowed to have them, not just the MC.
Whether people like it or not is subjective of course, but that's why the dev made it optional.
But I can understand adding the scene/reference to the scene for lore purposes.
