In the poster, Rap Monster looks out the window of a bus with a sad expression. His message says, "It's not the right time, so I'll just look at you from afar behind you." It's speculated the posters are for BTS' rumored drama, which was also rumored to be called 'Love Yourself'.
As previously reported, the "Love Yourself" series is scheduled to continue into 2018 as a follow-up to their 'The Most Beautiful Moment in Life', 'Wings', and 'You Never Walk Alone' series.
BTS are likely making a comeback this September with a new album under the "Love Yourself" concept, so stay tuned!
