Obviously the story told in this VN is fucking extreme. It's fiction after all.
However, in real life there are really crazy similar stories. I've experienced two up close. One when I was a teenager, I was hanging out with a group for a while where there was a loser who was humiliated beyond belief. I remember that one time they put him in a garbage container, and they threw him down a steep street. And the craziest thing is one time they forced him to stay still while they pissed on his leg. And the fucking loser kept hanging out with them and said they were his friends. They humiliate you and you say they're your friends? Sorry man, but you don't deserve anything else.
And the other story is about two colleagues at my office where one of them fucks the other's wife, and the cuckold says it's okay. That they're friends. I can't fucking wrap my head around it. If a guy fucks my wife, the first thing I do is send my wife to hell. And the second is that the guy can get his ass kicked. Coworker or not, friend or not, but that person ceases to exist for me.
So, believe it or not, there are fucking losers out there who allow themselves to be humiliated and trampled on, and on top of that they thank their bullies.
