Hi, I'm the translator for this game! Figured I'd leave my thoughts!
First off, to be objective, this game has around 124 CG's and four base sections, along with a CG Room, additional content, and scenes from the heroine's perspective. It has a story that it takes the time to develop, and between the story and the scenes, there's a lot of content to enjoy. It took me about 3 months to translate if I account for breaks in-between. The game spends a decent chunk of time actually being a game and making you care about characters and their motivations, or lack thereof for some, especially the plight of Ex and his rampant emotions, which is what makes the NTR in this game very nice.
The art is overall pretty good, nothing too special, but what gives this game its edge is the dialogue and the scenarios. Most NTR's put the protagonist in a position of power before slowly taking that power away; this game does the opposite. You start unable to do anything about the woman you fall in love with, get into a relationship with her, and start exploring your sex life with her, becoming the person to decide what happens with your NTR fetish, and I find that fascinating as a concept.
The dialogue also doesn't skimp out; one of the largest H-scenes is nearly 300 lines long, and it provides a decent amount of scenarios in and of itself; a lot of H-scenes are not too far behind that length too.
If you enjoy NTR this is a pretty hefty title to indulge in, and I'd fully recommend it for what it offers.
