Just loved it as a whole. Lee Jae Wook is one of my favourite actors, I didn't really like the idea of Goo Ah Ra, because I hardly ever finish dramas with her in it, but I was plesantly surprised. As for the rest of the cast and all of their acting I really liked it, they really were giving their best.
The plot was great and all, for me a little to many things that were unnecessary, and the ending was just weird. But overall I liked the mood the drama had, that's why I think it's worth re-watching and gave it a whooping 9.5 stars.
