Well, usually Instagram will notify you if someone has viewed your story. It'll show you a list of people who have seen it. Also, if they interact with it by sending a direct message or leaving a comment, that's a sign they saw it.
To be honest, it's quite difficult to be certain if someone has viewed your story. Different platforms have different features, but rarely do they offer a straightforward way to know for sure.
It's not always easy to know for sure. Sometimes there might be indicators like comments or likes, but they don't guarantee that the person actually saw the whole story.
Sometimes you can. Many social media platforms have features that notify you if someone views your story, but it depends on the specific platform and its settings.
Not always. It varies by the social media platform you're using. Some will notify you if the person is a close friend or has interacted with you frequently, but for others, there might be no notification at all.
It might be Iruka - sensei. Iruka was one of the first people to recognize Naruto for who he was and give him a sense of belonging. If Iruka were to die, Naruto would remember all those early days of support and kindness. His death would break Naruto's heart as it would be like losing a part of his family, the family that accepted him when no one else did.
One possible plot could be that Naruto witnesses the death of a fellow ninja from his village during a battle. Maybe it's someone he has trained with or has a friendly rivalry. This would cause him to cry as he feels a deep sense of loss for his comrade and also blames himself for not being able to protect them.
The neighbor might be a bit surprised at first. If it's a friendly neighbor, they might give a compliment like 'You look great in that bathing suit!'. Or they could start a conversation about where to buy such a nice bathing suit.
