When it comes to the party he specifically asked if his sister could come along, only to immediately ditch her while also telling her not to drink at a party, which even Piper pointed out was unreasonable.
Never said he was always 100% right and never wrong about how he acted in the story, especially toward his lil sister at the party, BUT he was just looking out for her as an older brother should do, making sure she won't get drunk enough to let some random, horny dickhead take advantage of her. And he does let her drink, if the player makes the choice, so I'd say he was only too much of an overprotective big bro' in that situation, not an insufferable guy.
As for Piper at no point did I defend her. Besides she isn't "his woman" he has known her for all of 10 minutes between the coffee shop and party, hell they didn't even go to the party together. She asks him to dance and he refuses and she starts playing mind games, which he realizes and still indulges her.
You and I are both reasonable guys sharing our opinions on what WE would've done in his place or what WE think it was the best decision in the given context, but you forget that the MC's still affected to some degree by his harsh past as an introverted fat guy who got humiliated for being fat and lazy and whatever on many occasions even by his own damn father. If not for Charlie and Barron, the guy would still be 'a fat loser', as his dad so
politely called him a lot, being walked over and humiliated by all kinds of idiots and arrogant bitches, and that sounds depressing asf, if you think about it, so him screwing up and not being completely rational in some situations like the party incident is something you could expect from a guy like him, but you can calmly walk away too if you don't like the KO approach.
About his reaction there... I never said Piper was
his woman, BUT he was interested in her and she reciprocated his interest, so him going all territorial on that drunk idiot is what some guys would do too IRL, especially after being taunted by the idiot. Don't tell me you wouldn't be pissed if you had a smokin' hot woman like her reciprocating your advances and some random nobody popped up trying to steal her from you, cuz I would be pissed asf lol.
Is it rude to have rough sex with someone who wants rough sex?? But it is pretty dumb to stick your dick in that brand of crazy.
Yeah, but he didn't know she's into that type of trashy fuckers that scream trouble from a few miles away until he fucked her, so he's excused for falling for the big titties,
like most of us would've.
There's obviously no problem with a woman liking a good rough fucking, but hearing her say how she's into controlling, abusive guys should be a big red flag for the guy and a guarantee of all sorts of trouble coming for her ass in a fucked up relationship like that.
