It could also be someone who has a secret crush on you. They are so interested in you that they make sure to be the first to see any new stories you share, hoping to get a glimpse into your world and feel closer to you.
He could be attracted to you. Your stories give him a chance to peek into your world, and he enjoys that. He may be looking for common interests or just likes seeing what you're up to.
There could be several reasons. Maybe he's your biggest fan and is always eager to see what you post. It might also be that he has notifications turned on for your stories and got the alert before others.
He could be really busy. If he has a lot on his plate, he might not have the time to check out your stories. For example, he could be swamped with work, schoolwork, or other personal matters.
Another reason could be that he is just a very observant person. He wants to stay updated on what's going on in the lives of people around him, and for some reason, your stories are more appealing to him. Maybe you have a unique style of presenting things in your stories that he enjoys. It could also be that he is trying to be supportive, especially if you are friends or part of the same community.
It could be that he's not really interested in that kind of content or doesn't think it's relevant to him. Or perhaps he didn't even notice that you shared the stories.
