Okay so I was re-watching all EXO MVs in chronological order to see if I could understand the whole story better, and I noticed something that kind of seems like useless information but still hella creepy, to say the least. (I don’t know if anyone has said it before, but I haven’t seen it so I’m sharing anyway)
First of all, let’s consider this as a clock:

Luhan would be 1, Chen would be 2, Xiumin would be 3, Lay would be 4, Kris would be 5, Tao would be 6 (from 1 to 6, the right side of the clock, EXO-M);
Sehun would be 7, Chanyeol would be 8, Baekhyun would be 9, Suho would be 10, D.O would be 11, Kai would be 12 (from 7 to 12, left side of the clock, EXO-K).
Now, keeping these numbers in mind, if we keep watching the MV, near the end we will notice that K and M realities are like a two-faced mirror, and 6 pairs containing one member of K (in reality K) and one member of M (in reality M), mirror each other, forming pairs.
First pair: Sehun and Tao
Sehun has a monarch butterfly land in his finger. After that, it lands on Tao’s finger in his reality.
Second pair: Chanyeol and Kris
Chanyeol makes wings of flame for himself. After that, Kris catches a burning feather from his wings in his reality.
Third pair: Kai and Luhan
We see Kai getting to Luhan, in a dark space with a bunch of orbs. Even though we can see Kai teleporting to other members earlier in the MV, Luhan is the only member in M reality that Kai gets to.
Fourth pair: Suho and Xiumin
After splashing the mirror with water, Suho wipes it and sees Xiumin’s reflection.
Fifth pair: Baekhyun and Lay
Baekhyun sends a beam of light toward a mirror, and Lay sees it through another mirror in his reality.
Sixth pair: D.O and Chen
D.O makes the earth shake, and as we see in the end, D.O’s image and Chen’s are mirrored upside down, with the grounds touching, meaning that Chen felt the earth shake in his reality too.
Now it’s where it gets weird.
Remember those numbers we assigned them from the clock? Well, if we add the numbers of each pair, that’s what we get:
Sehun (7) + Tao (6) = 13
Chanyeol (8) + Kris (5) = 13
Kai (12) + Luhan (1) = 13
Suho (10) + Xiumin (3) = 13
Baekhyun (9) + Lay (4) = 13
D.O (11) + Chen (2) = 13
Could this be a coincidence? Sure, but doesn’t look like it. Do I know where the number 13 comes into play? Not really. But still I thought it was worth mentioning. Feel free to use this as a basis for any theories you might come up with!
