I really want to like this game a lot more than I do, and I already like it a lot. It is *this close* to perfection, but it stumbles in some aspects. I think if you're a fan of NTR, especially hidden NTR, you'll probably still like a lot of what this game offers, but it has its issues. My whole experience with this game could be summed up by that one Director Krennic gif from Rogue One.
The art and animations here are really, really good. I was surprised to see the AI CG tag here, because this is one of very few games I've seen that doesn't immediately look AI generated, though you can see the tells of it in some parts (fairly generic "hentai" style, overly glossy rendering, hyper-detailed but "off" musculature, etc). I think a lot of editing work has been done here though, and the Live-2D animations really do a ton of heavy lifting to make it look beautiful. Personally, knowing that AI was used to generate some amount of the images does make me feel a little more poorly towards the art, but it's so great for the most part that I can't actually bring myself to be all that upset. I'd love for the animators to have fully hand-made art to work with. This is the type of game that just looking through the gallery at alternate scene variations is a great time.
The story premise for the game is pretty typical NTR stuff: wife is blackmailed by the boss to be his "special secretary" and NTR ensues. There's a few curves here and there regarding who is doing the NTR, but it's all pretty by the numbers. That's not a bad thing per se, but it's nothing mind blowing, and it starts to feel a little contrived towards the end, especially when you have pretty much all the evidence you could ever need to chieve your goals, but you gotta wait until the story says it's time to end. There are some choices to be made, but only a scant few, and they only change which ending you get. The endings only have story changes and a single, unanimated CG as differences, so there's not a huge reward for multiple playthroughs. You're gonna get access to all the scenes just by following the story (minus variations that unlock with different outfits). 
The gameplay is where I have the most issues, and I say that because it is so very close to being amazing. It is essetially a scene hunter game, where you look for your wife to get evidence that something bad is happening. You eventually get access to various "Spirit Stones" that allow you to see scenes with varying clarity, from seeing through desks and clothes, to straight up invisibility. But my absolute favourite is the second level of stone that shows you a silhouette animation of what your wife is doing at the time. It has the potential to be an amazing hidden NTR mechanic.
What pulls the gameplay down is how you attain the stones. The real gameplay loop of the game is scene hunting and following the (essentially completely linear) plot. But the game forces a money grinding aspect on you, partly for story reasons, partly to give it something akin to actual gameplay. Each time slot gives you the chance to shake people down for debt repayments in the form of a "click the button on the green part of the bar" minigame. It's boring and earns basically no money. The best possible payout (from only a handful of the available NPCs) can get you maybe one of the top level stones. It's a tedious addition to add some level of interactability that makes the game feel terrible to play legitimately. I don't know if I'd have bothered trying to see as much of the game as I did if I didn't cheat in spirit stones. And that's what makes me think the game is so close to amazing, but falls short. Because hunting for the scenes using the abilities is great stuff. Being able to use a stone to see that your wife is currently in a scene but you can't tell where and have to guess based on the silhouette's context is so good. If the spirit stone abilities were infinite use (or the money making wasn't garbage and better integrated into the gameplay loop), then it would have made the game infinitely better.
The other problem I have is that the game is effectively entirely linear. I call it a "scene hunter" but 9 times out of 10 you aren't actually "hunting" for scenes, you're just following the story and grabbing the scenes along the way. The scenes are well animated, but there is a lack of agency outside a few choices that don't really change all that much (and I think one of the choices is bugged and doesn't actually lead to the appropriate ending). In the few moments where you truly are searching for the scenes, using the stones abilities and exploring the map, the game is excellent hidden NTR material. Once again, so, so close to greatness.
My only other "complaint" (and it's so minor it really isn't shouldn't be called that) is that for a mostly hidden NTR game, there are some scenes that we as a player are shown that ruin the secrecy aspect. I'd have preferred those scenes to be cut and for us to only see things from the protagonist's POV. But that's mostly a personal preference, as I much prefer NTR stories that hide anything the protagonist doesn't see.
All in all, as I've said repeatedly, I *almost* love this game. I give it a high score because I really liked a hell of a lot of what this game does, I just wish it was better in some aspects. I do recommend playing it instead of just checking the gallery, but I also recommend using a money cheat or inventory editor to bypass the money grind. 
Make the game less linear and allow us to hunt for the scenes properly, remove the boring money making game and/or make the stones infinite use, and give the few choices available more meaningful impact, and I think you'd have a stellar experience here. Make finding the evidence you need to save your wife could be the core gameplay loop and not just a given of following the story. I'm just spitballing at this point because I see such great potential in the ideas explored here and want more. I'll be interested to see other games from this team in future, and I really hope they can make an incredible hidden NTR game someday.
