Ksyusha is in the tenth grade of school. She writes songs with herfriend Slava and dreams of attracting attention of a graduate with the surname Pogulyaev. The problem is that Ksyusha is fat, because of this she is the constant target for bullying. When the school announces a competition for participation in the school event, called «The last Bell», Ksyusha decides to take a chance. Having disgraced herself at the selection right in front of her crush, what made her a school meme, Ksyusha creates a channel in the social network, titled «Fatty» in order to troll herself in a way that others have never dreamt of.
