Much like the image of the butterfly and the soul in poetry and art, this series is superb, sweet, and compassionate with the grace and elegance of ballet as the frame for the deeply touching real story. The cast, direction, cinematography, and writing are outstanding: not a misstep anywhere as all involved work to tell the story of discovery, friendship, love, support, forgiveness, and healing. Filmed with such love and gentleness, this is one of Korea's finest series in its relatively short but brilliant history. I cried a lot, especially in the second half, but the tears were because I was so moved by the script, actors, and story they told so well. Strongly recommended.
