Don't you even dare cheat in her class. She'll know - she has eyes all over the school, and there's no way of escaping her clutches once she catches wind of your naughty tricks. Eventually, she'll call you into her classroom after hours for a chat, and you'll be in for a hellish tutoring session...

What pretty ticklish feet you have, little cheater! Looks like your devious teacher will be using them as her own personal canvas, scribbling equations and problems all over those soles. Keep up, and you'll be able to answer them easily, right? If you study up and pay attention, then your ticklish toes will be spared as your grades climb.

And if they don't improve, well, you can take summer classes for extra credit. She has a pair of stocks ready just for you~
