Erik is the mysterious, very attractive professor that that all the students have a crush on but they know nothing about him - not even his first name. So naturally they’re shocked when his twin five year olds burst into his classroom one day.
Everyone knows that Professor Lehnsherr is a stone cold fox. He is also known as the teacher who is most likely to engage in public humiliation and execution by failing grades, and so most students weigh out the pros and cons of taking his class very carefully.
Judging by the maximum capacity of “Intro to German Expressionism”, most students hold the merit of Professor Lehnsherr in a clinging turtleneck and tight trousers in very high esteem.
