Chart-topping superstar music group BTS thanked President Moon Jae-in on Thursday after the South Korean leader congratulated the band on their history-making U.S. chart achievement.

"Wow! We can now fully believe after seeing it with our own eyes. President Moon Jae-in, we thank you for congratulating BTS on its No. 1 victory on Billboard," the group tweeted in response, adding they were "deeply touched" by President Moon's acknowledgment.

"We will make efforts to move more people's heart going forward. Thank you very much," they continued.

On Monday (May 28), President Moon sent two tweets celebrating the septet's achievement after they hit No. 1 on the Billboard Hot 200 Chart, making them the first South Korean act to ever do so.

"At the very heart of BTS' outstanding dancing and singing is sincerity. This magical power turns grief into hope and differences into similarity. I congratulate BTS on topping the Billboard 200 with their album titled 'Love Yourself:Tear,'" Moon tweeted, per The Korea Times.
