I really regret not watching it earlier! I didn't think I'd get attached to this show so quickly, but, after the first episode, it pulled me in and I had to keep going. I never expected to cry watching this show. There's only a few shows that got me to cry, and this is one of them. But, this one is def worth the watch.
BTW it's so good see that how far actors like Shin Hye-sun has come. Starting from minor roles in School 2013 and Highschool King of Savvy to supporting role in Legend of the Blue and then lead roles now. She's a really Amazing Actress with all the hard work she does for every role like learning Ballet for this show. It's commendable. Love her and L.
