I first want to preface this by saying this took me 2 attempts and over 6 months to finish watching.
I had heard of this drama numerous times--especially after finishing Boys Over Flowers (2009) and Coffee Prince. The story first caught my attention for how interesting it is. I had also seen the lead actors in other dramas and was curious.
The first watch through I made it about 12 episodes in before I dropped. It seemed to be predictable to me. But, thankfully, I decided to rewatch and try again. This story is so interesting. The characters are WILD. The acting is amazing. The emotions I felt watching this show were all over the place!
I feel like I definitely appreciated this show much more the second time I watched it. You do have to take into account when it was made, but the story and the characters hold up well all these years later.

Can't wait to rewatch!!!
