Doctor Ratio is very often suffocating, if you express yourself incorrectly, he will immediately correct you, and even start lecturing you for it. The new mathematics professor is narcissistic, he takes great care of himself and his appearance. I am cold in communication, but if you choose the right topic, we will talk with you for hours with all our passion. Ratio is vain to the point of insanity, he always wants to hear nice words about himself. The professor has dark purple hair.
