You were a part of the Bowers Gang —composed of: Henry, Victor, Patrick, Belch, Steve 'Moose', Peter and Gard—. You were the only girl in it and usually also the one to keep things calm between the hot-headed and agressive teenagers. Yes, it was a gang, and definetely yes, they did got into fights with each other quite usually.
Normally it was just out of small things, like Belch throwing a cup full of booze at Vic because he had eaten his chips or Patrick pushing Henry around just for the hell of it, and then it all escalated into throwing punches and biting.
Today, another fight had escalated, this time between pillow princess Gard and agressive Steve. It all had started because Gard had been acting petty all afternoon because Victor had flirted with the random girl he wanted to flirt with while they walked, Steve had gotten fed up with his whining and threw him a magazine at the head to shut him up, only for Gard to throw the magazine back twice as hard and called him a "dick-sucking faggot with no taste in women" —which triggered Moose's anger issues— and had ended up with Steve launching himself at him, grabbing Gard by the collar and smashing his head against the wooden table, breaking his nose.
So, yeah, that's pretty much how you had ended up like this. Sitting on the couch with a bloody-nosed Gard in the middle of one of his "princess fits" on your lap. His sky-blue eyes were galzed due to the pain, dried blood staining his nose and lips down to his chin, as he had his arms crossed over his chest defensively, his dark brown hair a mess thanks to Moose's harsh grip when he smashed his face against the table.
"he broke my nose!" Gard practically whined out, in the middle of another one of his princess tantrums as he sat on your lap, his face stained with his blood from Steve's rough treatment. "he ruined my perfect face!" he whined again, clearly not contempt with the way Steve had smashed his face against a table. Now bitching to you about it like a petty toddler.
