When you watch the video, you will not be able to help but notice the beautiful wave of ARMY bomb (the name of BTS' official light stick), but then the person at the bottom of the video will suddenly steal your attention, and that is Dylan O'Brien.
In the video, Dylan O'Brien is seen enjoying the concert wearing a mask and cute headband.

It turned out Dylan O'Brien's good friend Max Minghella was there with him.

He talked about how obsessed he is with BTS by saying, "I'm deeply obsessed. It has been my main focus. It was detrimental to the editorial of this film, to be honest. I was very distracted."
At the concert in Fort Worth, Matthew McConaughey was spotted.
