"Room you can't get out of unless you have sex," it says.

I guess it means I'm gonna have to have sex with you, eh?

Just so you know, I'll never lay my hands on my own precious students, okay?

For now, we should wait until help arrives, huh.

Sensei...

Please take off your clothes at once.

Are you even listening to me?!

How about you, Sensei?! Would you rather stay in this room forever then?!

K-Konoka?!
