The show's production was filmed in North Sulawesi in November 2016. The show's participants who went to Indonesia at that time were from K-Pop group Infinite's Sungyeol, WJSN's Sungso, BTS's Jin as well as actors Kim Min Seok and Gong Myung. Indonesian local authorities welcomed the filming as it could help boost tourism in the area or help promote North Sulawesi's beautiful beaches, The Jakarta Post reported.

The SBS series "Law of the Jungle" showcases the show's fixed cast member Kim Byung Man and guests to survive in the wild. They use their abilities to make a temporary shelter by themselves, hunt for food and cook meals.

Just recently, Jin received medical treatment while filming the show. During the episode on Jan. 27, Friday, he was with Solbi and Sleepy as the three of them were separated from the team and left on their own.

Sleepy was not confident in diving while Solbi feared the water so the youngest of the trio, Jin plunged into the dark waters. They continued fishing while it was raining and they caught some fish.

When Jin returned to the boat, his face changed and he felt like vomiting. During the day he was not able to eat much while looking for food. Solbi and Sleepy assisted him while accepting treatment from the show's medical staff. The BTS member has won the hearts of the Law of the Jungle" production team, including PD Lee Se Young.

"The other cast members showered him with praise, saying that never in their lives have they seen an idol who is so innocent, bright, and overflowing with positive energy like Jin," Lee told Pop Herald. "He did so well that it made me wonder why it took him this long to venture into variety shows."
