Amber Park has been putting up with Marissa's bullying for over half a decade and now that they're in college, Amber wants nothing more than to keep her head down and get through her classes without being noticed. When a virus that compresses and shrinks those that catch it sweeps through town, she can't help but dream of a life where she gets to keep a tiny compressed Marissa for herself, to bully her the way she was bullied all those years. Her dreams are short lived however, and Amber ends up catching the virus herself, being declared a class B citizen, unable to live on her own. Now at just 4 inches tall, Amber's legal guardianship gets snatched out from under her parent's noses by Marissa who seems determined to make Amber's life a living hell. From treating her like a fashion accessory and a pet to actively playing with her like a toy, Marissa's bullying only gets worse once she has Amber under her full control. As Amber struggles to stay in one piece though, she can't help but notice that Marissa seems to care about her a lot more than she lets on...
