Kwon Sang-woo
Lee Hyo-won of "The Korea Times" commented that despite its familiar premise, "More Than Blue" "feels more classic than clichéd and the undying fidelity of the love-struck characters nostalgically evokes old romances. The talented actors also bring freshness to their parts, making them very believable and worthy of every ounce of one's empathy." Kwon Sang-woo in particular was singled out for his performance, with Lee commenting, "Kwon wins the audience's heart by bringing a certain tenderness to his character, suggesting a maturation in his acting, a palpable break away from his previous roles as a romantic tough guy."
