It has been revealed last October 2019 that Ong Seong Wu, Kang Ha Neul and Ahn Jae Hong are the newest casts of the 2nd season of Traveler.
Traveler is a travel variety program about celebrities going on a backpacking trip. The show lets the celebrities get full backpacking experience without so much interference from the production staff.
The first season featured Ryu Jun Yeol roaming around and enjoying the best of Cuba and was later joined by Lee Je Hoon. The two made memories as they find their true selves trying new things on their own as non-celebrities. 
Here are some pasilip to the idol/actor-turned-backpackers journey of these Oppas:
