they were showing a video on the screen and these two were sat cuddling with hae’s arm around hyukjae but then the video ended and they saw the camera was suddenly on them and immediately separated and sat up and tried to play it cool. lol look at their faces and demeanor completely change when they realize they are now the ones on the screen. lol. they got caught and they know it. in short, they stopped touching for the cameras, rendering your argument invalid.
