I watched SJK in Happy Camp and I love the part where he responded involuntarily to the 3 SHK imposters. His expression of relaxed look to heightened unconcealed anticipation and inner excitement (though he tried to keep a calm surface) when the MC teased him that there are some things they can't say but want to make it memorable for him......the entire scene is just priceless! I also got the vibes that he had even for a fleeting moment, hoped that it was his beloved SHK springing a wonderful surprise for him.
The unnerving anticipation... after all the hype by the MC.
