i’ve literally been looking for a movie similar to this but i also remember more that i think could’ve happened (if we’re talking about the same movie) i think i remember the blonde girl getting a flashback to her assault that there was multiple men seeing her get assaulted but not helping her, i remember she was the only girl in the party but i could be wrong. i also remember another girl with curly hair bullying her and possibly the one who spread the rumors of her because at the end of the movie she gets berated for doing something like that to her and lying about what she went through. it was definitely near 2015, i sadly do not know the name either but i remember so much from it.
