During Key’s Musical-inspired dance break, he tripped over his chair move and couldn’t stop laughing at his mistake (all members were laughing along with him). In the ment afterwards, they made him do it again and he did it perfectly. He couldn’t forgive himself earlier because he didn’t want to disappoint the audience. “I can now go home and sleep”, he said after re-doing the move.
He also asked everyone not to post this on twitter or else he will knock on everyone’s door. Taemin then encouraged shawols to post it so they will have a surprise at their doorstep.
