In the episode broadcast on July 12 of the variety show "Goblin's 10th Anniversary Trip" on tvN, the cast of the movie "Goblin" including Gong Yoo, Lee Dong Wook, Kim Go Eun and Yoo In Na together made a 2-day 1-night anniversary trip in Gangneung (Korea).
On the second day of the trip, the 4 actors continued to show harmony and were very comfortable with each other.
Gong Yoo starts the morning by preparing a refreshing meal and is praised by everyone as "chef Gong" who is extremely thoughtful.
The humorous verbal battles between Gong Yoo and Kim Go Eun, reminiscent of a couple who have lived together for many years, also bring a lot of laughter to the audience.
Meanwhile, Lee Dong Wook surprised Yoo In Na when preparing a delicate gift for her, thereby showing his warmth.
The episode also reveals many interesting personal stories of the "Goblin" cast. Audiences know that Gong Yoo and Lee Dong Wook actually knew each other long before collaborating in the movie "Goblin". Both served in the military and lived in the same unit as seniors - juniors.
Recalling that time, Lee Dong Wook said that at that time he was only a Private, and Gong Yoo was already one of the most senior soldiers in the unit with the rank of sergeant.
Gong Yoo humorously recounted that back then Lee Dong Wook almost didn't dare to look straight at him, even didn't dare to "step on his shadow".
After that, Lee Dong Wook made the whole studio burst into laughter when revealing: "Now I'll tell you, back then I washed all my underwear and Gong Yoo's socks".
Gong Yoo continued: "Even when folding clothes, he folded them very squarely and neatly.
Lee Dong Wook continued to answer: "To be precise, I am the one who supports him.
Hearing that, Gong Yoo smiled and corrected: "But only for a very short time. About 1-2 months... at most 4 months".

Gong Yoo further explained that although the two met when they enlisted, they only really became close after co-starring in the fantasy-romantic movie "Goblin" (or "Guardian: The lonely and great god) in 2016.
It was the time spent together through a hard filming schedule that helped the two become close friends.
In "Goblin", Gong Yoo plays Goblin while Lee Dong Wook is a Grim Reaper, verbal battles and "friendship of the enemy" between the two are one of the most loved points of the film.
That year, "Goblin" created a big fever in Korea, reaching the highest rating of 18.6% and is still considered one of the most loved Korean dramas of all time.
