For those who don’t know where to start, I spent a day traveling across the city and doing my best to see it through the eyes of a visiting fan, hopping between BTS-related landmarks that have turned the capital into a treasure hunt for ARMY.

BTS, or Bangtan Sonyeondan (Bulletproof Boy Scouts), debuted in 2013 under BigHit Entertainment, and they have taken the world by storm ever since.

The National Folk Museum will run a special program titled "K-Culture Folk Experience with BTS" through April 30, featuring traditional Korean folk games like "tuho" (arrow throwing), top spinning and "jegichagi," as seen on the group's YouTube show "Run BTS."

BTS is returning to the United States for the first time in nearly four years, and they're doing it with an intimate twist.
