Before that, Teen Top 'dongsaeng line' Niel, Ricky and Chanjo posed hilariously to wake up their fans! The three wrecked their faces and appeared funny. Chanjo uploaded it on his instagram account and wrote, "From morning, peekaboo ><".

Ricky also uploaded a selca with Changjo and wrote, "Fanservice'.
