The outdoor ads were spotted in Orlando, Florida and Santa Clara, California.
With no news yet of a stop in the Philippines, fans stormed the social media site with their prayers for BTS to include the country in the tour.
PH ARMYs also took the opportunity to poke fun at how they might not be able to afford the tickets if ever BTS performs in Manila.
The last time BTS staged a concert in the Philippines was in 2017 for their The Wings Tour. In December 2019, they announced their 2020 tour.
