BTS' concert in Brussels took place over two days, July 1–2, at King Baudouin Stadium. In addition to performing songs from their ARIRANG album, the group surprised fans on the first night by adding beloved tracks such as "Tomorrow" and "Boy With Luv" to the setlist, sending tens of thousands of concertgoers into a frenzy. In return for the members' pαѕѕionate performance, Belgian fans showed overwhelming enthusiasm and cheered them on throughout the more than two-hour concert.

The local fans' pαѕѕion left such a strong impression that the members repeatedly praised them during the ending ment. j-hope said Belgian ARMY would be one of the first five things that came to mind whenever he thought of Belgium, while RM expressed his admiration for the kindness and friendliness of the local people, saying BTS had an incredible time there. V even returned that affection by giving the green Celine zip-up jacket he was wearing to a fan who had been moved to tears.

Aside from the emotional moments on the concert's opening night, several behind-the-scenes details also υиєχρє¢тє∂ly became hot topics across social media. One of the biggest discussions centered around the water bottles that staff were seen emptying halfway before the show.

In a backstage video recently shared by fans, BTS staff can be seen opening each water bottle, pouring out roughly half of the water inside, loosely screwing the caps back on, and lining them up along the edge of the stage. The footage quickly sparked curiosity among ARMY, with many wondering why the group's drinking water was being handled that way.

However, fans later discovered that these were not the bottles BTS drank from. Instead, they were the bottles prepared for the members to throw or spray toward the au∂ιєnce during fun interaction segments. The bottles the members actually drank from were equipped with straws or marked with black labels and kept inside insulated containers near the side of the stage.

As such, the reason the other bottles were only half-filled was so that when the members squeezed or threw them, the water would scatter like a gentle shower rather than shooting out in a powerful stream that could нιт someone in the face, cause pain, or leave au∂ιєnce members completely soaked.

Another video featuring Jungkook during the concert further strengthened this explanation. At first, the bottle he was holding appeared to be completely full. Before throwing it toward the au∂ιєnce, however, he took several large sips from it before forcefully flinging the bottle, sending water spraying everywhere. It seems that BTS and their staff carefully considered even small details like this, aiming to create fun interactions while also ensuring the au∂ιєnce's safety and comfort.

From what initially looked like a simple backstage routine, fans once again praised BTS and their team for their thoughtfulness. To many ARMY, even the way the group prepares soмєтнing as ordinary as a water bottle reflects their dedication to giving fans the best and most memorable concert experience possible:

- They actually thought about our safety even when throwing water... BTS really pay attention to the smallest detail

- Turns out there was a thoughtful reason behind it. That's actually so sweet

- The first thing that popped into my head was some sort of poisoning conspiracy. I'm so dramatic

- It's such a small detail, but it shows how much they care about the au∂ιєnce's experience. Respect to BTS and the entire crew

- They really think of everything, don't they? Even the water bottles are prepared with fans' comfort in mind. That's why BTS concerts feel so special

- Every little interaction is carefully planned so everyone can have fun safely

- It's always the tiny details that remind me why BTS concerts are on another level
