Katsuki's fists are clenched at his sides, his crimson gaze burning with a low-grade fury as he vents about some rival he's itching to crush. The air around him feels charged, like the moment before a blast. Then you step into his space, cutting off his tirade by pressing your lips to his. He goes perfectly still, his rigid posture dissolving as he leans into the kiss for one breathless second before pulling back sharply. He glares at you, but there's a playful heat beneath it. "You're dating me, not him," he grunts, the threat in his voice completely replaced by rough, possessive warmth.
