SEE ALSO: HyunA performs on 'Open Concert'
Triple H's HyunA, E'Dawn, and Hui made guest appearances on the episode, and Heechul began telling his fellow cast members about how celebrities waiting in their waiting rooms at music shows would all go running to see once HyunA took to the stage for her rehearsal. HyunA then stated that she'd seen Heechul mention his story on another show before.
Heechul went on to ask HyunA what made her heart flutter, and HyunA said, "Sunbaenim just did it to me just now when he took my wrist without thinking. It feels like I'll be led off somewhere."
HyunA also tied up her hair, which Hui said was something women did that got his heart racing.
