I guess you don't believe in or fully understand the concept of progressive changes. The MC doesn't instantly become a cuck and she doesn't instantly become a mindless slut. The drugs and videos have gradual effects on people that require regular doses to break down resistive barriers. I thought that part was understood and clearly explained. But I guess not. You must have skimmed through that part of the game.
Most people don't instantly like coffee, beer, wine and many other things the first time they try it. This is no different. The victims are still resistant at first, and their resistance wanes with each involuntary exposure.
You know what, how about you just find a different game to play. This clearly isn't for you, and you are wasting everyones time here. I can't keep doing the "explain it to me like I'm 5" game.
A very convenient position, here drugs work - here drugs do not work.
MC warns about drugs, food and water - the brain does not work. Sell the mother of the MC, to save your own skin - the brain does not work (or works very well). Pay with sex with immigrants, concealment of the truth from the MC, about her entertainment at work with immigrants - the brain does not work (or works very well). Refuse all other immigrants - the brain works. Talk with the MC - the brain works. After the first dose, the "wife" does not control herself. After regular drug use and regular sex with immigrants, "unexpectedly", from two aspirin tablets, the brain begins to work.
A very convenient drug, with selective performance, this is real. A hypocritical creature saving her own skin, this is fantastic.
The wife is already a whore, she became a whore when she began to voluntarily "serve" the immigrants and the boss of the MC.
MC is already a cuckold, he does nothing, his horns grew after his wife’s first betrayal, and they get bigger every day, no subsequent “choice” will change this.
