I definitely don't agree with the critical reviews on here. Just because this series doesn't follow the usual format of traditional k-dramas, it doesn't automatically make this series bad. I actually like this series because of the fact that it tries to do something new. I really like the blend of romance and drama paired with this melancholic vibe. I was interested through out all the episodes, because it was so fresh.
This series also did a great job at casting. Bae Suzy is the perfect person for this role, her delivery was great in this. The story was also really interesting.
For me to have given this series a higher rating, I would have wanted to see more character development. I feel like some of the storylines were left open or unfinished. Some of the plotlines felt rushed or out of place as well. I wanted to know more about the characters and their reasons for doing what they did. Still, this was worth watching.
