How will I know whether someone has added me to their Instagram Close Friends?
You are the only person who has access to your “Close Friends” list. None of your followers will be able to see whether you’ve included them on the list. Likewise, you have no way of knowing whether someone has marked you as their Instagram close friend. You’ll only know when the person uploads a “Close Friends” story. The post will have a green circle around it, indicating that only the person’s close friends will be able to view the story.
