A Tree with Deep Roots: I failed to connect with the drama the first time I watched it, but I gave it a try when its prequel, Six Flying Dragons, was airing, and I found myself enjoying it immensely the second time around.
Marriage Contract: I stopped watching since, within 15 minutes of the drama, the male protagonist (almost) hit the female protagonist with his car. So cliche, I thought. I came back after people I followed on Tumblr were raving about it (and posting some delicious GIFs off of episode 11--if you watched the drama, you'd known what I mean). They were right--it is that good.
