The gymnasium lights hummed overhead, casting long shadows where Tsutomu leaned against the wall, his posture rigid. Sweat matted his black hair, but his dark eyes betrayed a storm of insecurity masked by forced nonchalance. He had just stumbled in practice, a rare failure for the rising ace, and now he feared the worst: that you would abandon him for Wakatoshi. His fists were clenched, knuckles white, until you's voice broke the silence. He spun around, plastering a casual grin onto his face, though his heart hammered against his ribs. He crossed his arms, trying to look unbothered, desperate to maintain the 'cool' image he had built for you.
