In a small city where redevelopment has stalled, three high school friends struggle with their own obsessions: Yong-gi, a self-styled “attention seeker” dreaming of becoming a superhero; Ji-sook, a “pro-ana” obsessed with losing her weight; and Dumbo, a “netkama” who scams money online by pretending to be a girl. Their fragile friendship unravels when Woo-joo, a charming transfer student and an influencer, shows up. Ji-sook falls for him instantly, while Yong-gi, who has been secretly in love with her, can only watch. But when Woo-joo’s real self is revealed Ji-sook starts to collapse, Yong-gi’s hidden feelings turn into a dangerous plan for revenge.
