Not all NTR games are absolutely stupid with total lack sense, also you can not just abandon logic and sense - people will not get invested in story, characters and thus ntr will lack kick. But fundamentally you often can overlook NTR stupidity because once the deed is done things go with the flow. That is not the case here, you experience the stupidity over and over again. I think the underlying problem is that the dev wants to eat cake and have cake. Asuna is supposed to be pure and innocent yet willingly cheat on MC. How is that supposed to make sense? I notice now that corruption tag is missing too.The answer is simple, you think too much when you think that you are going to find logic in an NTR game, if you have played part 1 you realize that it has a better narrative than the second part that is because some lols wanted the game to be as generic as possible protesting to focus more on this or that why I took out of the picture the work Fujino wanted to do
Another thing is that NTR games in general rigged against the MC. But again this is being overdone here. It is kinda like with plot armor, protag is being thrown out of the window but luckily falls on garbage bags. If its done once or twice it’s whatever. But the NTR plot armor here is being used over and over to the point of ridiculousness.
I give you that first part is better than second. I got bored of second, after several hours the plot hardly progressed, too many side characters I don’t care about and the same stupidity is being repeated over and over.
