Just want to let you know an important part in this choreo, they actually signed "thank you" 3:53 and 7:32 as well as "promise" 9:54 and 11:05 if you look closely at their hands ☺️
6:37 i agree with this, i always thought about this since i knew them but i don't really know how to explain it. If you watch the "without you" choreo-performance the way they walk still has the song texture so we don't lost the song's vibe.
