If you don't use the definition of the word then it no longer has the same meaning. There is a reason we have definitions for words. If not then you can say any word means whatever you want it to mean, such as cat is now a dog, love is now hate, car means sex. If you literally define the word unfaithful(broke his faith), you can't then go and say that person is still faithful because they are not, they can be still loyal but not faithful. Now if Alan had agreed to Clara sleeping/doing sexual stuff with other men then yes she could still be faithful as she wouldn't have broke his faith. So any criticism of the devs work is an attack now to you. I also said one of the reasons I didn't bring up the improper articulation was I didn't want to seem like I am attacking the dev. Simple fact is words have meanings for a reason, so that everyone knows what is being said.
There is a reason it's called a "faithful" route to have righteous/"faithful" choices. It would make it easier for some to forgive but that's where the corruption part comes in. What happens when she gets to where she enjoys it does she go that extra mile to make sure sex happens or becomes even sluttier during the scenes becoming more and more depraved. That's what your not looking at and that's where the corruption comes into play. Choice: do I just flirt/tease this guy to get access to somewhere or do I bang the shit out of him to get the same thing? Flirting/teasing doesn't work so seduction is now the only way but the corruption points would be awarded differently depending on original choice. So you can see where enough corruption and she would just start going straight to the sexual stuff over trying to remain "faithful" That complicated decision your talking about would come from Alan finding out she is doing a sexual path and enjoying the sex(the point of the corruption) rather than she just bangs out his enemy for the sake of NTR(typical trope).
What I was talking and asking about with the corruption is how is anything supposed to change the ending if there is nothing tying her to the MC she is either emotionally corrupted, leaves him for another, or physically corrupted where she leaves him because she enjoys sex with everyone but him. The only thing to "save" the marriage is a cuck/simp option to stay while she is still banging other people. That's why I started asking about how things were going corruption wise. If you only have 3 basic options for an ending- MC failure, MC revenge and MC stays married there isn't alot of option to change things other than the characters involved. All of that makes it pretty much a typical trope netorare game. I was looking for a story that wasn't bogged down with tropes and broke out of the normal shell of netorare, The dev pushes how choices matter and can save the marriage when in actuality they don't matter other than changing which characters "stay or go". I think more people are interested in X than the actual story. They want to know the who/why about x, screw the couple and their issues(other than the sex scenes) or how they get resolved.
This is your opinion and your entitled to it, others will have different opinions. The dev has as a path save the marriage but as many have already stated he gives no reason to try to save the marriage. They had problems before the mission and now with the mission those problems have gotten worse along with Clara's cheating. I'm not seeing alot of "love" between the couple. I mean you see Alan doing things to try to help Clara and make things better for them but not much on the flip side other than I'm doing this because someone threatened to kill my husband if I don't and starting to blame/hate him for everything that's happening. No real affection on Clara's side other than her internal monologue of "I still love Alan". I am waiting to see how it ends mainly because I'm curious about X, don't really care about the marriage as I have been given no reason to care about it.
