The promos for Legend of the Blue Sea feature leads Lee Min Ho and Jeon Ji Hyun solely to the point that it feels like they are the only characters in that drama. It’s an approach different than tvN is doing for it’s own fantasy themed tale Goblin, presenting the four leads with varying auras and charms for the audience to feast on. There’s the lonely Goblin Gong Yoo, melancholy grim reaper Lee Dong Wook, dreamy school girl Kim Go Eun, and bubbly Yoo In Na. Since it’s a K-drama there’s always a need to do a hair check and so far all four leads are sporting decent mops on their heads, with Kim Go Eun’s black longs straight hair the biggest visual jump from her last turn as the fried red haired lead in Cheese in the Trap.
