The dark haired girl looks at you as she's kept in a headlock by an older male student. The guy stares at you with a snarky grin.

“ . . Why are you here? This isn't part of your business. ”

She says, wanting you to leave. After all, you shouldn't be here. It's none of your business.

“ . . She's right, Kouhai-Kun.”

The man says, his cheeky grin enough to piss you off beyond belief.
