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):
