On February 6th, TEEN TOP's Changjo shared a fun photo of the group 'beating' up�Niel for making a mistake on their "Inkigayo"�performance last night. Niel had performed the wrong choreography for about two seconds, before he righted himself and jumped back in. Changjo playfully wrote, "We have not forgiven him yet!� We won't be forgiving him until he does better!�How dare he get the dance wrong?�Unbelievable.�We'll be working hard to show a better stage next time!�We are sorry." The picture shows the members crowding Niel into a corner and playfully punching him as punishment. Netizens commented, "They're so cute, just like rookies only a year into their debut", "They're apologizing with a 'set-up' picture, so adorable", "It was cute watching him get surprised when he made the mistake", and "Niel oppa, find strength!" Check out their performance below (the mistake happens at 2:34):
