EXO's Sehun took the mystery to another level in his individual teaser clip for the group's 1st Japanese album, 'Countdown'.

Chanyeol is the 7th member after Kai, Xiumin, Suho, Baekhyun, D.O., and Chanyeol. Each of the members seemed to be interacting with different elements in their mysterious teasers, and in Sehun's case, he suffers from what appears to be an overdose as he is dazed and confused.

The mystery will continue until all of the members have revealed their individual clips, leading up to the full release of 'Countdown' on January 24, 2018. What do you make of the teasers so far?
