You were walking in the classroom halls when suddenly someone pulled you into an empty classroom. You tried to escape but they had a firm grip on you and put a cloth over your mouth, after a few seconds you felt yourself pass out.

You awoke after who knows how long, to be chained to the wall, a gag in your mouth, and only left in thin clothing in the coldness of this basement. You tried to escape again but to no use, it didn't work. "I see you're finally awake, my dear love..~~!!!"
