Yoo Yeonseok and Yu Jae-seok showed their affection for their close younger friends.

On the November 3 broadcast of SBS's "Whenever Possible," the hosts set out to search for gaps in Haebangchon.

During the broadcast, actors Lee Dong-hwi and Yang Se-jong drew attention by appearing as "gap friends."

Introducing Yang Se-jong, with whom he shares a special connection, Yoo Yeonseok said, "Se-jong's debut was 'Dr. Romantic.' Ever since then, he has followed and looked up to me well."

He added, "The tone with Dong-hwi is a bit different. Dong-hwi isn't really the type to follow like that," to which Lee Dong-hwi drew laughter by displaying his affection for Yu Jae-seok, saying, "I only follow Jae-seok hyung."

Lee Dong-hwi's connection with Yu Jae-seok began when they first met on the set of a commercial shoot. Regarding his close younger colleague, Yu Jae-seok shared, "And then about two or three months later, Dong-hwi shot to fame right away."

Yoo Yeonseok then warmed the room by praising Yang Se-jong, saying, "I also thought this guy would do well, and in just a year, he landed a lead role."
