Gong Yoo (The Actor, Not His Character) Is Eun Tak's Number One Fan Behind The Scenes Of "Goblin"

Our resident goblin may have some competition, from the very actor who plays him.

In a newly released behind-the-scenes video of tvN’s “Goblin,” Gong Yoo and Kim Go Eun were all laughter as they practice their lines and walkthrough their actions.

While some of these scenes ended up being more emotional and serious in the actual drama, the same couldn’t be said about when they were practicing. The two actors were like beagles as they hilariously added their own adlibs and motions.

Gong Yoo said some of his lines in dialect and made Kim Go Eun crack up, but was in turn taken aback himself when the actress suddenly took a picture of him.

In another scene, their sudden hug made them laugh at the sound of the impact, and they continued to joke around during breaks.

At the very end, Gong Yoo turned into a photographer for “Eun Tak,” and couldn’t stop fawning over her beauty. While taking pictures, he kept asking the others, “Isn’t she pretty? She’s so pretty right?,” all with a mischievous look on his face.
