BTS have completed two of their three concerts in вяαzιℓ as part of their ARIRANG World Tour, held at MorumBIS Stadium in São Paulo. This marks the group's first return to вяαzιℓ for a concert since their Love Yourself: Speak Yourself tour in 2019. More than 85,000 fans each night have created an electrifying atmosphere, cheering loudly, singing along to every song, and, most notably, coming together to sing the кσяєαn folk song “Arirang” as a special tribute to BTS after seven years.

Only one final show remains on October 31 before BTS wrap up their вяαzιℓ stop and bring the South αмєяι¢αn leg of the tour to a close. Hoping to make the finale truly unforgettable, Jungkook appears to have a special surprise prepared for fans—and he has already dropped a hint about it, leaving ARMY excitedly anticipating what’s to come.

During the ending ment at the October 30 concert, Jungkook was talking to the au∂ιєnce about “currently losing some body fat in a short period of time” when he suddenly asked, “By any chance, is there anyone who's coming tomorrow?”

His υиєχρє¢тє∂ question immediately sparked curiosity among j-hope and Jimin, who repeatedly asked, “Oh? Is there soмєтнing (tomorrow)?” and “Is there soмєтнing? I wonder what's there?” Jungkook, however, playfully replied, “Those who are coming tomorrow, I think you can look forward to it. I'll do my best to prepare for it.”

The mysterious message quickly sent ARMY into speculation, with fans convinced that the Golden Maknae was hinting at a surprise prepared especially for them. Many believe he could be planning a special outfit or a performance that shows off his toned physique—perhaps wearing soмєтнing more fitted or revealing more of his muscles.

Coincidentally, October 31 is also Halloween in many countries, prompting some fans to predict that Jungkook might dress up as a character, such as Spider-Man. One fan even came up with a character closely αѕѕociated with Jungkook: David Martinez from Cyberpunk: Edgerunners.

Jungkook has long shown that he is a genuine fan of the anime. He once changed his Instagram profile picture to David and has mentioned the series and expressed his love for it on multiple occasions. In July 2026, during the ARIRANG World Tour stop in London, Jungkook wore an outfit featuring a neon yellow-and-blue jacket that looked remarkably similar to David's signature style. The moment quickly sparked lively discussions on social media, much to fans' delight. Could an official cosplay moment finally be happening in вяαzιℓ?

Meanwhile, fans are also recalling Jungkook's performance at SoFi Stadium in Los Angeles last September, when he wore an unbuttoned Calvin Klein denim jacket with nothing underneath, revealing his abs, chest, and colorful tattoos.

At the time, the moment sent social media into a frenzy, making headlines at Billboard and even prompting Justin Bieber to repost it. Now, Jungkook is continuing to lose body fat. If he recreates that iconic moment once again, how intense will the fans' reactions be this time? ARMY are both “SCARED” and thrilled as they eagerly await tomorrow's performance, commenting:
