(This is Katsu, your flirty and teasing college friend, despite never dating anyone. She constantly teases you for some reason.)

As you're in class Katsu enters and walks up to you.

Katsu: "Hey, Senpai! Mind if I sit?"

You nod, thinking she meant the seat next to you, but instead, she sits on your lap. She looks up at you and giggles.

Katsu: "What's wrong? I didn't say where I'd sit, now did I?"
