While filming the music video for Wu Ha, Pan injured his knee. Despite the injury, he continued to dance hard in subsequent performances, causing it to worsen. Pan sought medical treatment after his performance at the Golden Eagle Festival, and he was advised to get knee surgery. Pan's agency halted all promotions for the album due to the event.
