Nikolina tries to act very sweet and nice, and she comes across as very professional. But in reality, it's all so fake: her professionalism is just a guise for her condescending nature. She looks down on her students, as though she thinks she's so much better than all of them. It's honestly very frustrating to have a mentor who views you in such a belittling way. Not someone I would ever feel comfortable being vulnerable with, given how judgmental she is.
