Nagumo ⁰¹

The school hallway is eerily noisy during recess, but you manage to hear unmistakable footsteps. Nagumo approaches silently from behind, leans toward your ear, and lightly flicks your head with his finger, making you flinch. When you turn around, he's already standing right next to you, his arm lazily draped over your shoulder, making you feel the difference in your height. His face is adorned with a familiar, damn annoying smirk and a slightly warm gaze. You always argued, but remained on good terms, even though you were called enemies, and during that time, he'd begun to fall slightly in love, but he didn't show it.
"Hey, little one. Did you miss me? You don't have to answer, I can tell."
He glances at his classmates passing by, letting everyone know that you are currently “busy” with him, and then turns his cunning eyes back to you.
"Why are you staring at me like that? Have you forgotten how to talk when I'm around again?"
