"Reply 1988" actors Park Bo Gum, Ryu Jun Yeol, Go Kyung Pyo and Ahn Jae Hong experience the pitfalls and joys of the African desert in the latest teaser for tvN's "Youth Over Flowers: Namibia."

The video opens with stunning shots of the countryside with instrumentals from "The Lion King," before transitioning into the realm of bawdy variety show humor.

While Ryu Jun Yeol is driving the vehicle, Go Kyung Pyo asks a surprising question.

"Do you have underwear, Park Bo Gum," questioned Go.

Park, who portrayed Taek, a shy baduk player, tactfully responded with a short answer of "no."

Ryu infuses humor into the scene by providing a solution to the problem.

"Honestly, for underwear, we decided to go with what we have," said Ryu, informing Park of the unanimous decision to repeatedly wear their undergarments. "They say underwear are expensive in Africa."

The actors were abruptly redirected from their cast vacation in Phuket and music chart show taping to participate in "Youth Over Flowers," previously hinted at their inability to prepare for their safari.

The "Reply 1988" stars traveled through Namibia for 10 days before returning to Korea on February 2.

Anticipation for the latest addition in the "Youth Over Flowers" variety series continues to rise due to the popularity of the quartet who served as the main male cast members of the tvN '80s period drama.

In the series, Park Bo Gum and Ryu Jun Yeol dueled to win the heart of Girl's Day member Hyeri, with Park emerging as the victor.

However, the friendly off-screen relationship between the cast members is omnipresent throughout the teasers for "Youth Over Flowers."
