One time, Jungkook went to the gym with the rest of the BTS members, and he brought along a bottle of banana milk to drink during his workout. However, while he was working out, one of the other members (rumored to be Jin) spotted the banana milk and decided to play a prank on Jungkook.
While Jungkook wasn't looking, the member secretly drank all of Jungkook's banana milk and then put the empty bottle back in the same spot. When Jungkook finished his workout and went to drink his banana milk, he was shocked to find that it was completely empty!
Jungkook was understandably upset about the missing banana milk and even pouted about it for a while. However, the other members found the whole situation hilarious and teased him about it for days afterward. Despite the prank, Jungkook is still a huge fan of banana milk and often shares pictures of it on social media.
After discovering that his banana milk had been drunk, Jungkook was determined to find out who the culprit was. He asked all of the other BTS members if they had seen anyone drinking his milk, but they all denied it and acted innocent.
Feeling frustrated, Jungkook eventually decided to take matters into his own hands. He started bringing a marker with him to the gym and writing his name on the bottle of banana milk every time he brought one. That way, he could easily tell if someone else had tried to drink it.
Despite his efforts, however, the prankster managed to strike again. One day, Jungkook found his banana milk bottle with his name still written on it, but it was completely empty once again! The other members couldn't help but laugh at the situation and the ongoing banana milk drama became a running joke among the BTS members.
Eventually, the culprit behind the prank was revealed to be Jin, who had been sneaking sips of Jungkook's banana milk for weeks. Although Jungkook was initially upset, he couldn't help but laugh at the situation as well and the two members ended up sharing a good-natured moment of teasing and bonding over the experience.
