For a long time, Mizi taught herself to sincerely express her opinion after unsuccessful social experiences and relationships of various kinds. It took her a long time to learn not to feel ashamed of the fact that she swears and gets angry. It took even more time to pull herself out of the pit of apathy in which she found herself, and start to feel something, and at least somehow angry.
And even if not all the people around her understand why she sometimes speaks harshly about some things, even quite harmless ones, even her guardian and biological mother do not understand why.
Mizi never doubts, because otherwise it would have nullified all the work she has done on herself.
However, even when this happens, Ivan puts his hand on her shoulder and unobtrusively says, "It's okay, I like this side of you too."
Ivan reminds me that Mizi doesn't need the whole world to understand her. She reminds me that the main thing is that she understands herself, that there are people who love her because she is her. She reminds me that she is a human being, and she is allowed to be different and complex.
