Thank you for including the second half as well! I wasn't sure if it was okay to combine them in the request since they are technically individual episodes, but it looks like it worked out anyway. :)
Yes, the white sheets (long and short) are the stand-ins for what they used in the actual performance. The Beats behind the scene content is always so interesting to watch personally, because it's a chance to see how seriously they take their craft and random skills that they've perfected. ie: Changsub's finger snaps being a perfect metronome.
Minhyuk's mentioned before that he has trouble sleeping and that he used to work until he passed out, so him being up for 3 days unfortunately isn't surprising. He's also quite the perfectionist, all of Btob are to an extent, but he has very high standards for himself. Yeah, he looks so lean/small here, like obviously he's a pretty man, but the Minhyuk who is satisfied with his own health is so much more preferable. That applies to all the Beats as well, it's nice to see them looking much healthier as of late. Still the fact that it's already been 3 years since KLW feels insane...
Thank you for reacting to their Kingdom BTS!
