Jimin, a member of the group BTS, has sparked a conversation by revealing his firm packing philosophy: always carry plenty of underwear when traveling.

In a behind-the-scenes spoiler video for "Are You Sure?!" Season 2, released in the past on the official Disney+ Korea YouTube channel, Jimin and Jung Kook held a talk themed around travel keywords while playing Yut Nori. Under the keyword "Suitcase," Jung Kook listed toiletries, socks, and underwear as travel essentials, emphasizing the particular importance of "underwear."

Jimin advised, "Actually, underwear is more important than socks. If you're going on a trip for about a week, you should pack around 15 pairs." He added a practical reason based on his experience: "You might get wet, or you might not be able to do laundry in time. You never know what will happen at a travel destination." Jung Kook agreed with Jimin, saying, "You should pack a lot."

On this day, the two heightened fans' expectations by spoiling various episodes from Season 2, such as their paragliding experience in Zermatt, Switzerland, and a romantic motorcycle ride.
