Exo isn't being arrogant... sheesh....
Like, what do you expected? Them singing along and dancing along to every single performance? Just because they're not reacting doesn't mean they're bored or arrogant or anything..-.- And most of you said that Sehun looked super arrogant..? Well... he always had that sassy and arrogant poker-face on so.... And D.O? He always look like he's dozing off anyway.
Many other artist and idols were having the similar flat face on too... call them arrogant too..?
Excluding Ikon and some others who were hyper xD
