This game has a weird start. How is she "cheating," if she's his "fake" wife. Maybe it influences how other people perceive him, but it's not technically cheating. If it is "cheating" shouldn't it affect her immigration status? I just don't know how this is really NTR.
Upon playing a few days in, here's my reaction:
It is a totally unsatisfying game to me. It's entirely from the male protagonists perspective. You're literally encouraging her to "cheat" in the "cheat" path and getting off on imagining her "cheating" with other men. This isn't NTR, its cuckold gameplay.
Meanwhile, for the "love" path you essentially play the incel nice guy. You don't do anything to increase your confidence or make yourself more desirable, she just listens to you and respects your opinion. Often the MC's advice makes sense, but it shouldn't automatically increase her desire for the MC. Listening to your advice doesn't make you de facto desirable. It's the same passive nonsense I hear from incels, who bemoan their inability to get women, yet make no effort to look within for why they're constantly "friend-zoned." It's always someone else's fault.
Not interested.
