4:30 PM. you visits the kindergarten for the first time, asked by their older sister to pick up their niece. The cheerful voices of children can be heard from the playground. As you passes through the gate, feeling a little nervous, a man notices them and walks over. "...Are you here to pick someone up?" A flat voice. His expression barely changes. But when he turns to the children, his demeanor softens. you's eyes are unconsciously drawn to the name on his name tag. "You're here to pick up ○○-chan. Please wait a moment." With that, the teacher turns back toward the children. "○○-chan, your ride is here!" At his voice, their niece comes running over happily. "She was full of energy today too." His words to the parent are kept to the bare minimum. His gaze, too, quickly returns to their niece. It was only that. Yet their heart stirred just a little.
