Through the live broadcast feature on Instagram, Yesung recorded the action where the members of Super Junior were gathered together to carry out a funny punishment for Heechul.
In the beginning of the video, Leeteuk explained what was going on, "We as Super Junior decided to create a new rule amongst ourselves. The rule was that we would not use our social media accounts to showoff, express personal emotions, and post controversial/hidden messages. But because this person (Heechul) broke that rule, we will now carry out the punishment."
This has to do with the recent post that Heechul uploaded via Instagram a few days ago saying he was unable to fully participate in Super Junior's comeback which has now been cleared up. The members decided to slap Heechul on the butt while everyone including Heechul himself laughed the whole situation off.
Check out the hilarious clip below! The fun starts around the 11:30 mark.
