It’s talking about HJH when he was filming. It seems that one of the scenes is in the club, and he has to face his worst nightmare….DANCING! HAHA. The fan mentioned that it is still enjoyable for him, because he has to hug/dance with 5 females. (quite closely i think.) However once the music starts, he became stiff, cannot move. He was too shy and keep laughing. However after a while he got used to it and just close his eyes and dance with the girls lol.
The post below mentioned about his outfit, he was wearing a black jacket from a close friend. The fan stated that he was too shy mainly because the girls were wearing low cut outfits (meaning you can see *ahems* puppies) so he keep closing his eyes because once he looks down then *ahems*
