In episode 7 of Channel S and E Channel's variety program 'To the End! Solo Penalty Tour,' Yang Sang-guk joins as a travel companion and showcases unexpected charms in Nha Trang, Vietnam.

In this broadcast, Kim Dae-hee, Kim Jun-ho, Jang Dong-min, Yoo Se-yoon, and Hong In-gyu reunite in Nha Trang, Vietnam — the starting location of Season 1 — for the first time in three years. They enjoy the local scenery and take time to reminisce about the place where the first 'solo penalty game' and punishment began. At that moment, Yang Sang-guk appears at the beach pub where the members were resting and joins the full itinerary.

When Kim Jun-ho asks Yang Sang-guk about his overseas travel experience, Yang reveals that he has visited not only Vietnam but also Chile and the Uyuni Salt Flat in Bolivia, surprising everyone. He shows travel photos on his phone to prove he actually went. When Hong In-gyu suspects the photos might be AI-generated composites, Yang Sang-guk responds, "I'm telling you, there was no AI back then!" drawing laughter.

Additionally, Yang Sang-guk displays extensive knowledge about Vietnam and pulls out useful travel 'must-have items' from his crossbody bag, capturing the members' attention. Seeing this, Kim Jun-ho gives a thumbs up and says, "I thought Sang-guk was a country bumpkin, but he's a Vietnam expert."

Yang Sang-guk's unexpected charm and the travel items he personally prepared can be seen in episode 7 of 'To the End! Solo Penalty Tour,' airing on Saturday, July 18 at 9 p.m.
