One of the most well-written VNs on this site!
As a fan of the NTR genre, I've got to say that there are far too many bad VNs for every good one. I'm not entirely sure what intrigued me about this, but I decided to give it a try anyway, and it didn't take long to realise this is leagues above the vast majority of work in this space. The dev clearly has experience crafting stories and rendering 3D models.
From the initial release, every moment in the story matters. The relationship dynamics between the husband and wife are quickly established within one scene (if I remember correctly). The things they say, the glances they give - this dev knows how to show and not tell. While the boss is fairly one-dimensional (he's cocky, arrogant, and manipulative, but he's irresistible to women, and he's got it where it counts), I think that works for his position in the story, especially within the NTR genre. Besides, he could gain more depth in future updates.
The actual NTR dynamic in this story is different and adds a lot more intrigue. I won't spoil it, but let's just say the husband isn't naive and oblivious. The initial reason the NTR happens in the first place is established fast, and isn't done in a long-winded way, where we as readers can see where it's going, but the writer wants it to be drawn out for whatever reason. This is to the point, but not stupid. Also, the first scene hits so good, I don't think it could've been done in a better way.
The one flaw for me was the introduction to the mechanic. It felt very VN-y, and not grounded in (some level of) reality like the rest of the story was. It really felt like it was falling into a trope, which immediately put me off wanting that subplot to progress. However, I'm willing to let the dev do his thing because of how good the rest of the story is.
Some of the writing felt cliche, but most of those moments were charming, so I could enjoy it, rather than let it take me out of the story.
Overall, this story is great, and I can't wait for more!
