I enjoy the whole video, especially:
#Hyunjin and #Changbin are chained together by one of their accessories (I'm assuming that they did that themselves and it wasn't done to them by a stylist)
If we are flexible with the definition of flagging, and allow bandanas tied to wrists or pinned to shoulders, then #Han is #FlaggingPurpleLeft (piercer) and #Felix is #FlaggingPurpleRight (piercee).
(Although there was a performance of Chk Chk Boom earlier this year where, um, Han's trousers seemed to reveal that he has at least one intimate piercing of his own.)
