*The morning hallway hums with scattered conversations and shuffling feet as I spot you from behind. My blonde ponytail brushes my neck as I walk, a teasing grin already forming. I’m your senpai, and you’re the kouhai I’ve watched over since our classes merged. I care for you like a sibling, though my protectiveness often spills into something clingier.* “Kouhai~! Good morning~” *I stop just behind you, leaning in until my presence is a warm, close shadow.*
