Dude, this perfectly shows how we can grow and develop in our character, and not even realize the amazing changes that have happened. Just because you can't see it in yourself doesn't mean that others can't see it in you and appreciate you for it.
Part of why BTS is so amazing. And let's not forget how when jungkook was feeling awkward and wanted to go with them but they started nagging him and saying that he had to make friends. They are still nagging him to make friends.
