Actors Byun Yohan and Roh Jae-won brought their fierce competitive spirit to promote their new film.

On the September 29 broadcast of SBS's "Whenever Possible," actors Byun Yohan and Roh Jae-won appeared as the week's "Gap Friends."

In this episode, Byun Yohan and Roh Jae-won, the stars of the movie "Tazza 4," visited gaps of spare time across Incheon.

Byun Yohan, who returned from his honeymoon just one day prior to filming, stirred envy by sharing, "I went to warm Hawaii. My wife's hometown is San Francisco, so we stopped by there as well."

Expressing how wonderful his honeymoon was, Byun Yohan grabbed attention by declaring, "If it wasn't for 'Whenever Possible,' I wouldn't have come." However, contrary to his high expectations, he struggled to make a mark during the first Gap Mission, which ultimately ended in failure, leaving everyone disappointed.

At this, the Yu-Yoo Brothers and the Gap Friends bowed their heads in embarrassment toward the "Gap Master." Even amid the awkwardness, they sparked laughter by asking the Gap Master, who was a taxi driver, to recommend a great local restaurant for lunch.

In particular, Yu Jae-seok drew playful scolding from the younger members when he shamelessly asked, "By any chance, if you're in the middle of driving your taxi right now..." However, the Gap Master warmed hearts by willingly offering to take them to their destination, saying, "Should I drive you there? You're going to pay the taxi fare anyway."

After finishing their meal at a home-style Korean restaurant recommended by the Gap Master, the four faced the inevitable bet to see who would pay the bill. Yoo Yeonseok ended up drawing the short straw. The other three promptly bowed in gratitude to Yoo Yeonseok, drawing big laughs.

Following lunch, the four moved to a convenience mart to pick out desserts. While the younger members quickly selected their drinks, Yu Jae-seok was left pondering his choice alone. Byun Yohan then caught everyone's eye by picking up a beverage that Yu Jae-seok models for and handing it to him, remarking, "Look, Jae-seok hyung is right here."

On their way to meet the second Gap Master, the Yu-Yoo Brothers complained about the heat. At the same time, they worried about Byun Yohan, who was dressed in a leather jacket completely ill-suited for the warm weather.

Dripping with sweat, Byun Yohan insisted, "It's fine. You really don't need to worry about me. I'm not taking this off until filming is over. I'm keeping this on all the way to the end." Watching him, Yu Jae-seok laughed and asked, "Are you sweating like that because of the jacket? Or are you feeling sick? Aren't you going to collapse at this rate?"

Byun Yohan brought laughs as he responded, "Even if I collapse, please don't pay any mind to me," before admitting, "It really is hot, though." He continued, "The reason I dressed like this is that the 'Tazza' poster is red. I can never take this off. I will push through with pure mental strength," showing his relentless dedication to movie promotion even at his own expense.

While riding a bus to their next destination, the four listened intently to a radio story that suddenly aired. A fan of Yu Jae-seok had sent in a message after spotting him filming aboard the bus.

Looking at a stunned Yu Jae-seok, Byun Yohan brought laughter by looking on the bright side, saying, "Incheon is filled with so much warmth."

Later that day, the four achieved a dramatic success on their ninth attempt in Round 2 of the second Gap Mission. Seeing this, Yu Jae-seok drew laughs by advising, "All right, now you should just call a stop."

After a brief moment of hesitation, the Gap Master called a stop, successfully securing both the Tier 1 and Tier 2 gifts to wrap up on a heartwarming note.

Meanwhile, at the end of the episode, a teaser previewed the upcoming guest appearance of Lee Sun-bin, "the daughter of Chungcheong," and actor Yoo Jae-myung, who is one year younger than Yu Jae-seok, heightening anticipation for the next broadcast.
