I can't help but imagine what the show would have been like if all the groups were complete:
Ateez was missing Mingi, their second rapper, who was on a hiatus due to mental health.
BTOB were missing Hyunsik, Sungjae (in army) and Ilhoon (also in army, and no my mans didn't need to go to prison, although he is out of the group. Honestly, most of us Melody's still support him. All he did was smoke some weed. It's legal where I live. It's just too bad that its not legal in SK. Anyweh), so half the vocal line, rap line and their main producers were missing for them
Stray Kids were missing Hyunjin, one of their main dancers.
iKON was missing B.I (left the group due to a drug scandal too, turned out he only ever bought them,never used. That shit's in the past now. He's back in the music industry as a soloist. His stuff is amazing u should check it out. All the members still support him and follow him on insta. ) their main producer and 1/2 of their rapline.
Only the Boyz and SF9 were complete although some members missed out on some performances in the show due to injuries/ conflicting schedules. ;)
