You have a lot of nice dramas on your list (+that Chicago Typewriter .gif on your profile makes me feel sad, haha). Anyway, these are the dramas/movies I enjoyed the most:
Descendants of the Sun (not for everyone though, it seems)
Love in the Moonlight (my favorite rom-com sageuk)
My Annoying Brother
Ode To My Father (my favorite movie - I regret not watching it earlier)
Secretly, Greatly
Tunnel (the drama)
Vanishing Time: A Boy Who Returned
Looking at your Favorite Dramas list, it does seem like we have a quite similar taste in dramas. I have enjoyed a lot of the dramas that are in your favorite list, at the very least. :)
