My Weight Loss, Her Meltdown

I'm the heiress of the elite Graham family, and yet my life is like hell. After all, the rolls of fat keep clinging to my body. No matter how hard I try, I can never get rid of them. Even if I don't eat for the entire day, my weight still rises exponentially. When I'm on the verge of dying from organ failure, I see my parents showing up with the adopted daughter, Freya Graham, in front of my sick bed. Freya covers her nose while gazing at me with a mixture of smugness and disgust in her eyes. "Thank you so much for taking the brunt of the misfortune for me, Dakota! Otherwise, I'll be the one plagued by the fat! "Then again, you've already had it good. You've lived a lavish life for many years, after all. This lifestyle is something that you can never experience for the rest of your life!" I widen my eyes in shock. But it's because of my overwhelming emotions that I can't breathe at all. In the end, I die tragically with hatred in my eyes. It turns out I'm just the fake heiress who the Grahams have adopted. My purpose is to shoulder the misfortune that's meant for Freya this whole time! She gorges on food every day, only for all of her fat to accumulate on my body instead! When I open my eyes again, I've returned to the first day when I start putting on weight like mad. In this lifetime, since Freya doesn't want the body fat this badly, she might as well live her life as a living skeleton!
