it's more like-ok so first off the "novel" in question? Literally just a shitty self-indulgent rpf fic written by one of those "Nice, not like other girls" types if you know what I'm talking about? Like they think they're the sweet, selfless underdog victim but in reality they're a giant bitch who only sees people in one dimension, probably due to the stereotypes they see in media?
no yeah THAT'S the fic character A gets transported to. And basically it's like some girl at Character A's school was writing a RPF fic on like AO3 or a site like that and it was VERY obviously about everyone in her school. Like the names were slightly changed but other than that like-very obviously them. The main character in this RPF fic is obviously the girl writing it, and of COURSE she's the perfect, princess-y mary sue who all the dudes are gonna end up falling for right? Well the person who gets transported, Character A, who LITERALLY just checks out this fic because people in the school figure out that it's about them, yeah Character A's the VILLAIN in this RPF. So when she gets transported in, it's into the role of the villain.
So she didn't even HAVE a choice in the matter. ...what a way to go lol
So, alright. A random made character A, the villian of this entire thing. Bratty, snobby, whatever-this character thinks she's all that and every man is just gonna fall for her, what after that? As well, we really only have character's A side of the whole thing-
yeah no so basically Character A canonically in Random's story is yeah-bratty, vain, selfish, a jackass, etc. Character A in real life is literally none of those things and so when she gets transported into the story it's like "Wait is this how this person sees me cuz like I've never done-ANY of these things."
The reason WHY she's the villain in this story is that Character A is pretty, and fairly talented like she does sport-shit and stuff like that. So she's moderately well-liked in school and "Popular"...but obviously people aren't one dimensional so no, she's not a catty, slutty, condescending bitch she's just-a PERSON.
