Answer:
He believes that his nose has left his face through witchcraft
Explanation:
Russian Classico, The Nose was written in 1836 by Nikolai Gogol, narrating the story of an officer from Sao Petersburg, Major Kovaloff, whose nose one day leaves his face after developing his own life. His nose, now independent, begins to pretend to be a human.
Major Kovaloff can not understand why his nose left his face and the only explanation he finds is that he was targeted by witchcraft by the mother of the girl he was flirting with.
