Seo In Guk and the tribe headed out into the Gobi Desert to complete a mission, and they ended up eating a meal of grilled frogs. He stated, "To be honest, it was difficult to eat." The singer wasn't able to keep the frogs down, and he broke into a cold sweat and started coughing.
When the medical staff took a look at him, the doctor found Seo In Guk was suffering from severe fatigue as well as lack of nutrition, and he was given a saline drip.
He commented, "I didn't get sick because I came here. It's because I came right after filming a drama (MBC's 'Shopping King Louie'). I didn't rest, and I was physically exhausted when I came."
Hopefully, Seo In Guk feels better soon.
