Another reason could be related to his personal growth. He might be trying to master the power of the eye in private. Naruto has always been one to face challenges alone at first. By hiding his eye, he can focus on understanding and using its power without distractions or the pressure of others' expectations.
Alya may hide her feelings because she is not sure of them herself. In Russian novels, characters often struggle with self - discovery. She might be in a state of confusion about her own emotions and by hiding them, she is buying time to figure out what she really feels.
Maybe she finds Russian novels a private and profound world. In those complex stories and characters, she can bury her own feelings as if they are part of the fictional emotions in the novels. It could be a way for her to avoid directly expressing herself in real life.
I have no idea why she would do such a thing. It could be a sign of some serious mental or emotional issue, or maybe it was just a crazy one-off moment of bad judgment.
One possible reason could be for protection. Maybe there are threats out there targeting him, so by hiding his appearance, he can move around more freely without being recognized. For example, if there are rogue ninja who want to take revenge on him for past battles, hiding his face would make it difficult for them to track him down.
To gain an advantage. Just like in the original series where he often used surprise to his benefit. In fanfiction, hiding his power allows him to do the same. He can catch his opponents off - guard.
Naruto might hide his feelings because he doesn't want to burden others. He has been through a lot in his life, like being an orphan and facing discrimination in the village. He may think that sharing his negative feelings, such as loneliness or self - doubt, will make others worry about him. So, he chooses to keep them to himself and always show a positive, determined side to the people around him.
Maybe he is ashamed of it. Some past works might not be up to his current standards, or perhaps there are elements in the novel that he doesn't want to be associated with anymore.
There could be various reasons. Maybe she wants to work through it on her own first. Or it might involve something she's not proud of and is worried about your reaction.
She might use body language subtly. For example, she could avoid direct eye contact when she's feeling something strongly. In Russian novels, characters often convey complex emotions through such non - verbal cues.
