Gist:
KHD still feels like he can do something, when everyone else is tired and wanna go to sleep. YH realizes what the staff want and persuades KHD to go to bed when the light gets the brightest. When nobody dares to speak, he keeps telling the truth that everyone actually wants to go rest. Then YH talks about how his mom loves watching the show and told him to stay by KHD's side, cuz that's when he gets the most screen time -- like when they went fishing together (all the staff crack up). PD comments that YH is even sleeping next to KHD this time, to which YH answers, "Yes it's party time for her." When the light gets very bright, YH says "Good night," to everyone else's relief. :)
