Mario always thought himself as an average man, one who would never get far in life. Graduating college a single virgin doesn't help either. Mario never thought he would find the perfect woman for himself, but his whole life changes when Hitler becomes very sick. Hitler was supposed to go to an interview with the most famous entrepreneur in the US, Katy Perry, but Mario did it for him since he was very ill. Katy is almost immediately attracted to Mario, and Mario is obviously very flattered and feels the same way. But Katy is strange. Katy doesn't act like a normal person. She buys the weirdest things when she goes shopping, and almost never smiles for pictures. She tells Mario to stay away, but Mario cannot. Katy herself can't seem to follow her own rules either, insisting that they make out in the middle of a busy street. And so Katy and Mario get together in one flaming hot night of passion, burning "love" all around. But Mario learns things about Katy he wished he'd never known. And as he is thrown deeper and deeper into her sick world, he's not sure if this is what he wants. Little does Mario know he has enetered something he will never get out of. Katy wants the chubby man, and Katy will get the chubby man. Mario will be forced to go through a sick adventure, learning about Katy's past, and being pushed into her future. Mario will never forget the way the cold metal chains wrapped around his body...
