The protagonist, and by proxy the author, constantly spew on about responsibility and how they owe this and that to their wife and daughter unknowing that they can just.. simply not owe them anything. Letting the idea that you HAVE to do everything to try and repair your loveless marriage and your disappointing daughter possess you and dictate a majority of your actions is exactly what drove Robin away from them and towards Bell, and despite what the novel would have you believe, yes it's a good thing.

There's no need to stay in a sinking ship if you no longer wish to go down with the crew, you shouldn't feel compelled to sink with them and yet you also shouldn't feel compelled to hop ship at all costs, the game, and therefore the author, tried at every turn to demean Robin and the player for choosing Bell over Sally and Melody thinking you NEED to demean yourself for other people constantly, you can never do what you actually want to do just what other people expect from you and what you're doing is WRONG and you should NEVER cheat. Unsurprisingly, embracing the ability to do what you actually want to do isn't "wrong" and will never be "wrong". The author even attempts to throw in a final gotcha in the form of the ending twist to try and make you feel bad for wanting to be with Bell despite her proving to be the superior woman to Sally again and again.

Despite how the game tries to paint it, everyone was better for Bell in the end. Robin & Bell finally found somebody to love, Robin and Sally get their daughter back, and Melody gets to disappear just like she wanted to. If you're even slightly an open-minded person it's a very obvious happy ending and it's unfortunate that the author couldn't see that in their own visual novel.
