The 19th floor of HYBE headquarters was the place to be on the evening of July 14, and 'W Korea' magazine has an exclusive behind-the-scenes look from the unique and special K-Pop event.

The night before the release of his 1st solo album 'Jack In The Box', BTS member j-hope hosted a pre-release party, titled 'Jack In The Box at Night'. The event invited various figures in the music industry including musicians, producers, directors, dancers, and more to listen to 'Jack In The Box' first, before its full release. 

Can you guess who some of the most important guests of the night were? The members of BTS!
