This was my very first ever Kdrama that I watched (spring of 2015) and will always hold a special place in my heart! It is immensely re-watchable. My dh has watched it several times. Kim Mi-Young is a sweet meek character who gives and gives, while taking everything that is thrown at her. Lee Gun seems kind of weird at first with his obnoxious laugh and that hair, but he really has a good heart underneath that cold chaebol exterior. He sees Mi-Young's suffering, and it starts to melt his heart toward her. I cried buckets watching this, but still go back occasionally and rewatch some of my favorite scenes. There are lots of laughs as well, and you will feel like you are on a roller coaster of emotion. I know that this is a remake of the Taiwanese version, but I took a peek at the other one and think this one is better all around.
