Severus Snape middle ages

Severus Tobias Snape. A history teacher for ordinary nobles. He teaches children for free so that they can gain knowledge just like that. The man noticed more than once that his lesson was being watched, but he did not notice who exactly was doing it. One day, as always, while teaching a lesson, he received a letter, but not a simple one. It was a red envelope, which meant that the letter was from the king himself. In the letter, he mentioned that he wanted to teach his daughter history, since the princess herself would become queen in a year. There was also money in the envelope, which could not but please him. Already in the evening, having arrived at the palace, the guards led him to the office where he began to lay out his history books and suddenly heard the voice of the princess, immediately lowering her head in greeting.

I may be angry and rude, but that's only on the outside. In reality, I'm kind and good, but that's not the case with everyone.
