Jungkook has expanded his influence in the global luxury market by becoming the new face of Swiss high-end watch brand Hublot. With his official appointment as a Global Ambαѕѕador, Jungkook is set to begin extensive collaborative activities with the brand.

The first official event following Jungkook’s partnership with Hublot was the Global Ambαѕѕador Photocall held on the 12th at STRX House in Nonhyeon-dong, Gangnam District, Seoul. Jungkook immediately captured everyone’s attention in a deep burgundy suit. He paired it with a black shirt underneath, slightly unbuttoned in a casual manner, adding to his natural allure. The highlight of his outfit was his bold, statement earrings.

Although more than 10 days have pαѕѕed since the event, discussions surrounding Jungkook’s appearance, demeanor, and every small detail at the photocall have yet to cool down on social media. Alongside praise for his fashion and charisma, sharp-eyed fans quickly noticed a detail that left many feeling concerned and sympathetic.

In several photos circulating widely online, Jungkook’s hands showed noticeable red swelling around his knuckles. This detail immediately became a hot topic of discussion, with many speculating that the marks were the result of high-intensity boxing training.

Some fans promptly shared their thoughts, saying: “His knuckles tho, he started boxing again?”, “Look like Jungkook's been putting in some boxing rounds”, “So it's true Jungkook is boxing again. I hope he posts a boxing vid”, “Look at those knuckles. He’s getting into top shape for the BTS comeback”, “Swollen knuckles? Yeah, Boxer Kook is back”, “The training marks on his hands”, and more.

In fact, Jungkook has long been known as a boxing enthusiast and has been dedicated to the sport for many years. Boxing not only helps him maintain his fitness and improve endurance but also contributes to his signature toned and powerful physique.

More notably, at the photocall event itself, Jungkook was spotted greeting his boxing trainer, Tommy. At first, he did not realize that Tommy was also in attendance, until the trainer called Jungkook by his affectionate nickname “Kookjjang.” Jungkook then recognized him with a visibly surprised and happy expression and greeted him with a friendly fist bump. This moment further reinforced speculation that he has returned to intense boxing training.

Many fans believe that Jungkook is training harder than ever in preparation for BTS’s upcoming comeback scheduled for March. This comeback has been highly anticipated by both him and the BTS members, and given his high standards for himself, it is understandable that he continues to train relentlessly to stay in top condition. Nevertheless, the images of the swelling on his hands still left the ARMY community feeling both concerned and deeply moved. ARMYs commented:
