"Huh, that's right, the guy from before seemed to have come from the rooftop. What was he doing up there?"
It took the sweet and cute girl quite a while to snap out of her numerous imaginations and reveries, and she remembered a practical issue, her eyes moving slightly.
Smoking?
No, that's not right, his body had no smell of smoke at all.
He couldn't have been going to do "that," could he?
She had just heard in a recent report that a student, because of an impulse towards a beautiful teacher during class, took the chance during the break to run to the bathroom to do... that.
With a bit of a wicked interest, the girl thought to herself, her eyes moving again as she suddenly turned around and dashed up, heading straight for the rooftop.
"Huh? The rooftop door is locked? And there's no toilet paper or anything like that on the ground?"
