Exo has a song called Lucky.. they performed it live many times, even at recent fancons. The choreo is iconic. If u follow the storyline, they were caught by the red force their enemy, experimented on..mybe thats why they lost their power. In continuation, their Love Me Right japanese mv, u can see their clones or the x-exo learning to live like humans😅
Kai is the distraction so everyone can escape. Then all he has to do is teleport out of there ✌😁 Ceaser Oh's whole group guide goes into Exo's storyline a little. And it is good at giving a sense of what is going on in it. Also it's good to watch that whole group guide too, to give a more indepth background on Exo.
