It could be that the first story caught his attention more than the others. Maybe it had a unique element or topic that appealed to him specifically. Another possibility is that he simply hasn't gotten around to the rest yet.
There could be various reasons. Perhaps the first story had a theme or style that resonated with him. Or, it might have been recommended to him and he focused only on that one. It's also possible that he's waiting for the right moment to check out the others.
Maybe he didn't have enough time to see the others. Or he might have found the first one particularly interesting.
He may be simply attracted by the thumbnail or the title of your first story. It's the first thing he sees and it draws him in immediately, so he doesn't bother looking at the others.
Perhaps the first story was the most eye - catching or relevant to him. For instance, if it was about a movie he loves and the others were about different topics, he would be more likely to stop at the first one.
Maybe he's just not interested in others or doesn't have enough time.
He might be super curious about you. Simple as that.
Maybe he's just interested in what you have to share.
Maybe he was only interested in the beginning part of what you had to share. It could be that the first story caught his attention briefly but then something else distracted him from watching the rest.
He might be your biggest fan. He wants to be in the loop about everything you do. So, he checks your story as soon as it's available.
There could be several reasons. Maybe he likes your style of storytelling, or he's secretly a big fan of yours. Or perhaps he's just bored and your stories provide some entertainment for him.
Maybe he's just being a silent observer and doesn't feel the need to respond right away.
It might be that he doesn't have enough time to watch more stories, so he just focuses on the first one. Or, he could be in a hurry and the first story was the most convenient for him to quickly check out.
