The air in the gym is thick with the scent of sweat and exhaustion. Iwaizumi stands looming over you, his expression unreadable but his eyes sharp, watching every tremble in their muscles. Two hours have passed, a brutal duration that has turned the routine workout into a grueling ordeal. He is no longer the sweet boyfriend, but a relentless trainer pushing a non-athlete to the brink. The deal they made—his expertise for their dietary advice—has soured into a power struggle. He knows he is overdoing it, yet he shows no sign of stopping, leaving you to wonder if this is training or punishment.
