My boyfriend thought I was too fat at 121 pounds. I signed up for a gym and started working out like crazy, but the more I tried to lose weight, the more I gained. Meanwhile, my best friend, Chloe Woods, was doing late-night eating streams every single day, stuffing herself with steaks, seafood, and greasy takeout. Not only did she not gain weight, she dropped from 154 pounds to 143. When my boyfriend started tearing into me even worse than before, I suddenly heard the tabby cat’s voice in my head. “You idiot. Chloe’s got you trapped in a weight-swap system. “No matter how hard you try to lose weight, she’s the one getting thinner. Every pound you lose is a pound she drops. She’s trying to ruin you.” I froze and turned to look at my best friend, Chloe. She was staring at my boyfriend without even trying to hide it, her eyes full of admiration. Then the tabby’s voice exploded in my ears again. “Chloe is obsessed with that trashy loser. Once she gets skinny, the two of them will hook up. Then they'll team up to get you killed and spend your settlement money living a happy life.” The moment I learned the truth, I smiled. Since my so-called best friend wanted to be skinny that badly, if I made her whole body weigh less than 50 pounds, she’d probably be very grateful to me, right?

My fiancé had a thing for girls who were tiny, pale, and fragile-looking. A month before our wedding, he demanded that I slim down to 80 pounds. So, I starved myself, counted every calorie, and spent my days at the gym. Alas, the harder I tried to lose weight, the heavier I got. … Meanwhile, the girl I'd been supporting stuffed herself with burgers, milkshakes, and late-night takeout every day. Yet, she kept getting thinner. On our wedding day, my fiancé became disgusted the second he laid eyes on me and promptly decided that I was too fat to be his bride. Then, he dumped me and replaced me with the scholarship girl right there at the altar. Not long after, the rapid weight gain wrecked my health. One complication led to another. As I lay on my deathbed, she finally came to gloat. "You idiot," she cooed at me mockingly. "I linked you to a weight-swap system. It doesn't matter how hard you diet because the weight loss always goes to me." Then, everything went black. … When I opened my eyes again, I had returned to the time before the wedding. As my eyes focused, I saw the same girl standing in front of me, nagging me to lose weight. I smiled, but scoffed internally. 'If you want to be skinny that badly, fine. However, I'll make sure you end up weighing five pounds this time around, ashes and all.'
