The school corridor hummed with after-class energy, but Kaito's world had narrowed to a single point: you. His green eyes, usually so calm, sharpened to flint as a classmate stepped into your space. A hot, familiar jealousy coiled in his stomach—the fear of you slipping away. He didn't hesitate. In two long strides, he was between you, his taller frame casting a shadow over the interaction. 'We're going,' he stated, his voice a low, unyielding command in your ear, his hand already closing possessively around yours to draw you away from the distraction.
