“Is it the next song??”— Fan speculations run wild over BTS’ j-hope sporting a ‘Surf’ belt in the latest ‘MONA LISA’ press photos

On March 21, 2025, the South Korean media outlet Sports World released a press release featuring a photo of BTS’s j-hope for MONA LISA. While the press photo seemed like a standard promotional image, fans noticed a subtle detail that sparked speculation.

The K-pop idol wore a belt with the word "Surf" on its buckle, which fans quickly pointed out. In the MONA LISA music video, his belt also displayed the song’s title. This has led to theories suggesting that "Surf" could be his next track.

"Is it the next song??," an X user commented.

Fans shared their excitement about the hint—

"I genuinely believe that SURF could be the next big fish in the pond," a fan shared.

"Most probably. Our man has been hinting in every MV," a fan remarked.

Fans noted that MONA LISA and Sweet Dreams had subtle hints before their release that went unnoticed. They now believe the same might be occurring with "Surf."

"I think so Sweet dreams and mona lisa were always in front of our faces, and we didn't realize," a user mentioned.

"He did this with Mona Lisa too," a person said.

"Wait a min his belt has " Surf" & not Monalisa on it 🤔 Does that mean the next track is called " Surf "?," a viewer noted.
