Exactly. It's twisted and nonsensical. That's what makes it fun. You have this chick who plays the act of the loyal, loving wife. She convinces and tells herself that it's real, that she loves no one but her husband... but the guy sucks in bed. So she goes out to someone else behind his back and then returns to him while pretending. Like I said, it's bullshit but it's the hot type of bullshit. Delusional maybe but it's not necessarily fake love, just twisted. That's why I used the words "twistedly wholesome" since she does return to him in the end. The main reason I don't like the girl falling in love and losing her heart to the other dude is because that's it. Game Over. She's not the guy's anymore so what's the point? It doesn't sting or matter anymore since she couldn't care less about him any longer. It loses the whole "betrayal" thing in my eyes in that case. In the way I see things where she continues "loving" the guy then it's a constant and continuous loop. Delusional on her end and it's absolutely not pure love but it's a twisted sort of love in a way. Her heart is only for her guy... her body is for everyone else.
I'm sure I could explain my thinking better but I'm no grand poet to explain this in better terms, I'm just an idiot with a specific preference for this type of fetish lol
