my RAILWAY theory:
at the start of the mv, we see black-chan (wearing all black). he's being violent, he's fighting, probably eating human flesh, etc. cool stuff. he's lowkey kinda hot but that's also irrelevant to the theory. he's basically just being really violent.
but then!
we see white-chan near the end of the mv (in all white), and he pushed black-chan down into the ground (literally), and fights him (and wins).
my theory is that black-chan is irl-chan's emotions. remember the concert where chan broke down and said he would protect the staff, the members, the fans, aka everyone? and remember how he's always been open about how he would do anything to protect those he loves??
i think black-chan is that side of him; the side that will go to extremes (including murder) to protect those he loves. it's his inner emotions.
meanwhile, white-chan is his rationale: the part that says 'bro stfu and sit down, murder will get you in jail'. white-chan beats black-chan bcs his rationale prevents him from doing anything drastic.
(you could also interpret this as white-chan being idol-chan, and how him being an idol prevents him from going to drastic measures for his family/friends bcs it would ruin his idol image).
now the interesting part of this theory is that at the end of mv, we see white-chan getting up from his chair, but then he puts on a black coat. he's no longer just white-chan; he's both. also: if you've noticed, black-chan and white-chan have their 'fake' eyes in opposite eyes; you need both of them for him to have 2 normal eyes.
i think this is his way of saying: "i'm a mix of my internal emotions and my rationale". he can be both, and though his rationale will maintain control of his emotions and prevent them from going too far, he will ALWAYS have both.
thanks for listening to my (confusing) ted talk hehe
