Photos of Jungkook providing fan service during the Day 2 sound check

During the sound check on the second day of the concert in Las Vegas, USA

This is a photo of BTS member Jungkook giving fan service lol

The expression looks like that because it was taken in an instant, but it's incredibly powerful.

He was in the middle of a performance lol. He came up wearing a black track zip-up.

It's Jungkook with his sleeves rolled up a little, showing off his tough guy arm tattoo.
