Chemistry between the leading actors is one of the most important thing that compels audience to watch a drama or movie. Even the best plot can’t save a drama that features a couple with zero chemistry.

Lee Minho surprised us when he revealed that he and actress Jun Jihyun were not chummy at first while shooting Legend of the Blue Sea. He said, “Honestly, we did not get close right away. It was a little awkward and uncomfortable at first, but fortunately, while we were shooting overseas, we got really close.”

He added, “We’ve become friends to the point that we’d break into laughter by looking at each other.”

The actor revealed that Jihyun being on board the production was one of the reasons he chose to act in the drama. He said, “I chose Legend as my comeback project because of ‘ParkJinJun’ – Park Ji Eun, the screenwriter of My Love From The Star; Jin Hyuk, whom I worked with for The Inheritors; and actress Jun Jihyun.”

Legend of the Blue Sea aired in South Korea last night, and the first episode chalked up ratings as high as 15.4% – even higher than Descendants of the Sun! The first episode will air on ONE tonight at 8.10pm.
