The video seems to have been taken by a fan who focused on Chanyeol during EXO's '2014 MAMA' stage. Chanyeol doesn't look like he's doing too well to start with, and at the moment where there's a member switch for the stage, Chanyeol rushes off, fumbles for a water bottle, and looks like he might even be vomiting a little. His stylists rush to his side immediately, fanning him and fixing his makeup, but he manages to trudge back up to the stage.

After the stage, Chanyeol seems to have a hard time even walking himself off the stage, barely able to hold himself up. The video has brought to question a lot of things, most importantly why Chanyeol was performing if he was so sick.

Hopefully Chanyeol will get enough rest to recover before EXO's upcoming comeback.
