"The King: Eternal Monarch" actors Lee Min Ho and Woo Do showcased their close friendship in a new photo posted on their social media accounts!

The two actors just recently worked alongside each other in the SBS drama "The King: Eternal Monarch." In this drama, Lee Min Ho portrayed the character of Emperor Lee Gon, the monarch from a different universe. On the other hand, Woo Do Hwan played dual characters - one is the emperor's bodyguard in one universe and the other character is an ordinary public service worker in the parallel universe.

On July 5, Lee Min Ho posted a picture of him and Woo Do Hwan, embracing each other, showing their fans that despite the conclusion of the drama, they remain close, like how King Gon trusts his "Unbreakable Sword."

Also in the photo, Woo Do Hwan's head is already shaved, noting that he's prepared for his enlistment. In the caption, Lee Min Ho called Woo Do Hwan "Yeong," which is the name of Woo Do Hwan in the drama. The actor stated, "Yeong, I truly wish that you become the best shooter in the field."

At the same time, Woo Do Hwan did not let the chance pass and also posted the same photo on his social media account and wrote, "I will go for now and will come back soon, your Highness."

Woo Do Hwan is scheduled to enlist today as an active-duty soldier.

Best of luck to you, Woo Do Hwan!
