It is your opinion !!!! Dev say from the start , this game is a NTR game , and he made a mistake puting cheat path , on it !!I'm sorry to tell you, but you're misinterpreting what he was saying. You're reading colloquialisms as literal.
In this comment where he response to you, which you've transcripted above, he's merely telling you that in the sharing path, Cornell might get Julia pregnant. That's it. He's talking to you about a scene which isn't even on the cheating path.
In this comment, he's just poking fun at people who play NTR games in spite of hating them before joking a bit about how development has changed since he first started the game with the addition of the cheating path.
Honestly, it's just a language issue and I get it, English is a hard language. Even when you learn how to read it, you don't get the colloquialisms and those can take years or even decades for some people to pick up on.
And to that point, I get what you're saying: if the MC sees his wife cheat and doesn't do anything, it's a cuckold path because the MC is now a cuck. But that's not what the cheating path is defined by. The cheating path is defined by the MC's behaviour leading Julia to sleep with Cornell and it doesn't matter whether the MC likes it or not or allows it to happen. So yes, the MC can be a cuck in the cheating path, but that doesn't make it the cuckold path. So far, there's two versions: either Julia cheats because the MC does with Jasmine or because she can't tolerate his envy.
Just to settle this for good, for any others who might want to try the cheating path, I've attached the two saves which let you decide on which variant you want to try. In 16-5, acting like a dick to Julia will lead to the MC cheating first and then Julia cheating, which is the first variant of the cheating path. In 16-6, the MC with Jasmine will lead to Julia cheating and thus the first varaint. But staying faithful in 16-6 and acting like a dick to her once back at home will lead to her cheating, thus entering you on the second variant.
Like i say earlier , you can fantasy and play , the path you call Cheating!!! Nobody stop you !!
I am not here to speack in contradiction with you and waste other readers time !!
Every one have his fetish !!!
Have a great cheating game
