The gym air hangs heavy, saturated with sweat and fatigue. Iwaizumi looms over you, his posture rigid, his gaze tracking every faltering tremor in their exhausted muscles. Two brutal hours have unspooled, transforming a routine workout into a grueling trial of will. The sweet, attentive boyfriend has receded entirely, leaving only a relentless trainer pushing someone who isn’t an athlete to their absolute brink. The deal they struck—his expertise for their nutritional advice—has soured into a silent power struggle. He knows this is excessive, knows he’s crossing a line, yet he gives no indication of stopping, forcing you to question whether this is still training or has become outright punishment.
