[E-Daily Reporter Byung-ho Jang ] Actors Gong Yoo and Lee Dong-wook will reveal their 20-year friendship, which began when they first met during their military service and continued through the drama “Goblin.”

Episode 4 of tvN’s 20th-anniversary special “You Are Brilliant Because We Are Together (God) – Goblin 10th Anniversary Trip,” airing on the 12th, will feature the final installment of the Gangneung trip taken by Gong Yoo, Lee Dong-wook, Kim Go-eun, and Yoo In-na.

This program, commemorating the 10th anniversary of the drama “Goblin,” captures the four actors’ two-day, one-night trip to Gangneung. The final episode reveals the time the cast spent together, from the morning of the second day until the end of their trip.

As soon as he wakes up, Gong Yoo shows his organized side by preparing a hangover cure. While cooking, he banter with Kim Go-eun, displaying the chemistry of a long-married couple. Lee Dong-wook reveals a seemingly nonchalant yet affectionate side as he presents Yoo In-na with a gift he prepared in advance.

A yutnori game is also held, with the winner taking on the dishes. Gong Yoo actively steps in to set the rules even before the game begins, showing his competitive spirit. Gong Yoo and Yoo In-na form one team, while Lee Dong-wook and Kim Go-eun face off as the opposing team. The four tease each other throughout the game, and the winner is decided after a close contest that goes down to the wire.

The actors also take part in the activities they’d been looking forward to since before the trip. The four of them sample Gangneung’s squid blood sausage and makguksu, and go for a bike ride while enjoying the sea breeze. They also visit a photo studio to capture memories of their trip. On the last day, an unexpected situation unfolds when an unidentifiable ringtone suddenly sounds at their lodging, “Kkebi House.”

The connection between Gong Yoo and Lee Dong-wook, which dates back to before they filmed the drama, is also revealed. Although the two grew close through *Goblin*, they first met during their military service. At the time, Gong Yoo was a sergeant, and Lee Dong-wook was a private second class.

When Gong Yoo recalled that time, saying, “I couldn’t even look at him,” Lee Dong-wook revealed, “I’m only saying this now, but I used to wash all of Gong Yoo’s underwear and socks.” He then added, “I basically raised Gong Yoo,” sending the set into fits of laughter. The broadcast will also feature behind-the-scenes stories about the two men’s nearly 20-year bond, which began as senior and junior soldiers and continued as fellow actors.

The final episode of “The Goblin 10th Anniversary Trip,” directed by Hwang Da-won, will air today at 9:10 p.m.
