Nothing in story books but women hate it in real life in a situation where it's their lover.
It's basic evolutionary psychology. Even if the beta is just trying to protect her to feel like a hero she reacts like he's trying to fight off her mate and replace him.
It's established fact that when girls are watching men are far less likely to back down from a fight. It's observable in teenage boys or drunks outside clubs. A playful standoff that was going nowhere can quickly escalate when a girl gets in the middle to 'break them up'. If the beta is a fat faggot like in OP who couldn't beat him in a straight fight the already violently angry male will need iron willpower to not take his passive aggressive fake challenge at face value.
No one thinks straight in a stand off like that not even girls.
Not only that is extremely stupid, seeing the girl will turn on you 50%+ of the times, but it is extremely beta and white knighty
Even worse posting your beat up face on a feminist subreddit to get compliments, kek, this guy is pathetic
Your supposed to protect your girl. As in if some crazy nigger hobo comes up and tries to hold up your girl, you're supposed to step in and beat his ass.
You don't have to white knight for other girls who put themselves in an abusive relationship.
