Who are the "spare-time friends" that left the Yu-Yu brothers flustered?

On the September 15 broadcast of SBS's Whenever Possible, the Yu-Yu brothers were shown looking taken aback by the appearance of the spare-time friends.

On this day, Yoo Yeon-seok said regarding the spare-time friends, "According to the intel I heard, it's an actor I've worked with on a project before," adding, "They're cast members from the movie Tazza. It's Byun Yohan and Roh Jae-won, right?"

In response, the production team showed a subtle smile, prompting Yoo Yeon-seok to brag, "I don't know why you're trying to hide it. I'm practically Tazza right now."

Yoo Yeon-seok was greatly flustered when the real spare-time friends appeared. Contrary to his expectations, the spare-time friends turned out to be actor Yoo Seung-ho and singer Young K.

Yoo Yeon-seok then flusteredly explained, "No, I got a tip on who's appearing in a movie opening these days," leading Yu Jae-seok to tease him by asking, "Where on earth did you get such rotten intel?", drawing roaring laughter.
