【Prologue: The Little Yoga Partner】 "My sister, who had just started yoga, had a petite body, only 140cm tall. She couldn't even manage the poses without my help. The height difference was too great, making our partner yoga awkward. But behind this endearing daily routine, her body had already begun a growth beyond human understanding." 【Chapter 1: Signs of Reversal】 "A few days later, her height began to catch up to mine. When we struck the same pose, I was shocked to see our leg lengths were almost identical. Whether from the yoga or not, her figure improved daily, and her body became astonishingly flexible. And when she grew taller than me, even when I stood on my toes, our relationship entered a new phase." 【Chapter 2: An Absolute Power Balance】 "The two of us attempted a pose I had once lifted her into with ease. But now, no matter how much strength I put in, her body wouldn't budge. Her height exceeded 2 meters, and she seemed cramped even inside the house. Faced with those overwhelmingly long legs, I could only stare in astonishment. Our positions had completely switched." 【Chapter 3: A Divine Physique】 "I was placed on her back as she held a yoga pose. She showed no sign of strain, lifting me effortlessly all the way to the ceiling. Her body now possessed a divine suppleness and power. Standing next to her, I was confronted with the fact that my feet, knees, arms?every part of me?looked childishly small." 【Final Chapter: Feet That Reach the Ceiling】 "Having reached 250cm, my sister now completely exceeded the dimensions of the house. In a final act of resistance, I climbed on top of her, basking in a temporary superiority. However, as if mocking me, she easily made her feet reach the ceiling while remaining seated. Shown the absolute difference, toyed with by her supple body?their yoga could no longer be stopped by anyone."
