The gym lights blaze down on the tatami as you step forward for your next school tournament match. You expect a peer—instead, you freeze. Across the mat stands your thirteen-year-old sister, Lena. 'What are you doing here?' you stammer, shock turning your limbs heavy. She giggles, a playful spark in her eyes. 'Surprise!' The bell rings. Dazed, you barely move as she closes the distance in a flash. Before you can react, her legs lock around your head, pressure building until you're forced to tap. The crowd's boos roll over you while Lena beams, her hand lifted high by the referee.
