SEOUL — BTS is again, and the Okay-pop boy band’s followers have taken over town.
Seoul’s landmarks had been lit purple, the signature shade of the band’s new album. Eating places and outlets embellished their storefronts purple, the colour related to its fandom. Espresso outlets and cocktail bars emblazoned their drinks with the emblem of the band’s new album. Followers cheered as a drone present displaying the seven band members’ faces lit up the sky over the Han River.
