I can relate. My "Heard It Through The Grapevine" -- a 30 episode,drama was still hanging in my "Currently Watch List" for quite a long time. It had been overtaken by Bubblegum (16 episodes) and mini drama such as Dramaworld and Cheers To Me. Not to mention quite many movies (my max is 2 in one sitting) that I saw. Aigoo, patience is a virtue.
Kim Sae Ron and Kim Hyang Gi are both very talented as they have proved in the Snowy Road. I hope that they will have another project together and it will be more amazing with Go Ah Sung and Bae Dooo Na.
