You are manipulating the concepts of cause and effect. The reason for all the decisions of the MC is a consequence of manipulation on the part of Steph. All decisions of the MC are based on false information.That's your opinion. Not all of us felt that way about the wife.
The MC is not the "good guy" in this game. Never was. The whole premise at the beginning of the game was "I want to fuck a hot woman who isn't my wife. Let's see if I can manipulate my wife into fucking another guy so that she can't get mad at me fucking the other woman." There are a couple of ways that the MC tries to do this, depending on which path/confidence you play, but it always starts with the MC wanting to get his wife to give him permission to fuck another woman.
The problem is that people who self-inserted experienced a bunch of cognitive dissonance that they didn't expect. She wasn't a "shitty" person, she was the person created by these actions/reactions. MC tries to force her into being with someone else, she does it, then some players got mad that they succeeded at the thing they tried to do. Then they complained that the game wasn't going the way they wanted. Some players wanted to have their cake and eat it too.
All that said, why didn't the people who think the "main woman of the game is shitty" or "an unlikeable piece of shit" just move on? Honestly, I would love to hear one person explain to me why they kept playing the minute they decided that they didn't like the main female protagonist.
It all started at a Christmas party. Steph's ego demanded to rise above Tori in the group sex skills competition. Steph boasted to a stranger (at the party they were not yet friends) about her rich gangbang experience. She can’t tell her husband, but she can brag to Tori. Steph is the cause of all events.
The role of the MC in the game is determined by three functions: the MC agrees, the MC is happy, the MC forgives everything. If Steph piles up a bunch of crap, the MC will justify it HIMSELF, he never scolds, objects or argues with Steph. A natural question arises: what is Steph afraid of? If on Friday night, after work, the MC sees Steph fucking the football team at home, he will sit with the eyes of an imbecile, the smile of a zombie and forgive everything. Steph absolutely does not know MS, with whom she has been married for four years.
It's funny to watch the miracle of the Immaculate Conception happen on a Friday night. This evening Steph turns into an immaculate virgin. Suddenly all Steph’s vast gangbang experience disappears. She doesn't know that she can get drunk, she doesn't know that she loses control when adding alcohol + sex. Steph turns into a teenager who goes to a party for the first time, tries alcohol for the first time, sees a dick for the first time. Mysteriously, all of Steph's previous experiences disappear. For three days, Steph pretends to be a virgin who accidentally entered a brothel (there is a photo of Steph “the best worker” on the wall).
MC CANNOT MANIPULATE Steph, you cannot manipulate a person who knows ALL the information. It is Steph who is manipulating MC, all decisions and actions of MC are based on false information. Steph could ALWAYS stop things, admit it (if Steph only needs the MC's opinion), but she always only wants a gangbang. On Saturday morning, Steph doesn't demand the MC to talk, she demands Donny's dick. All MC decisions are one big mistake, the REASON for the error is Steph’s lies.
