Yu Jae-seok gave a warm welcome to his favorite younger colleague.

On the September 8 broadcast of SBS's "Whenever Possible", Joo Woo-jae and John Park appeared as gap friends.

During the broadcast, Yu Jae-seok reacted to Joo Woo-jae's appearance by saying, "Ah, Woo-jae, what is this?" In response, Joo Woo-jae grumbled, "Did you see that? Didn't I tell you? He wouldn't have any reaction at all. Why did they tell me to hide this?"

Then Yu Jae-seok welcomed his close younger colleague in his own signature style, saying, "Why are you coming to someone else's workplace?" He then greeted John Park cheerfully, calling him "Ah, Park John."

Joo Woo-jae, who purposely sat as far away from Yu Jae-seok as possible, shared, "I thought to myself that I would never appear as a guest on another show hosted by Jae-seok hyung. Because he doesn't treat guests like guests at all."

He continued, mentioning that he had previously appeared as a guest on another show hosted by Yu Jae-seok, and explained why he broke his resolution: "He didn't even ask any questions throughout the entire filming. So I was making up things to talk about all by myself and thought, 'I should never come out again,' but because of John Park, I ended up coming out together."
