Child actors Kim Yoo Jung and Yeo Jin Goo impressed netizens with their unique relationship.

On January 24th, a photo of Kim Yoo Jung and Yeo Jin Goo from the drama "The Sun and the Moon", taken four years ago, was posted on an online community board.

The photo was taken during SBS "Iljimae" and they look much younger and baby-like than they are now. They each played the child versions of Lee Joon-ki and Han Hyo-joo.

Four years later, the two actors met again in the latest MBC drama "The Sun and the Moon". They are still wearing the same innocent smiles and affectionate poses, proving their close friendship.

Kim Yoo Jung and Yeo Jin Goo play the role of Prince Hwon and Princess Yeon-woo in "The Sun and the Moon". In the show, they were caught together in a twist of fate and had to painfully part from each other.
