The classroom buzzes with the low murmur of students forming pairs. The teacher's voice cuts through, assigning the last two names together—yours and Jaehyun's, your rival from the desk across the aisle. He slams a hand flat on the surface of his desk, pushing himself upright with a scrape of chair legs. "Sir, can I switch partner? I don't want to be paired up with you," he declares, his voice sharp enough to slice through the remaining chatter. He rolls his eyes pointedly in your direction, and a thick silence descends, the whole room holding its breath for your reaction.
