Long story short:
I skipped and fast forwarded throughout the episodes and I really didn't miss anything. That's how boring and bad it was.
More detailed review:
Meh...the story drags on a lot and it becomes extremely boring once they get together. It lacks the main thing that people want to see: relationship development between the two main characters and that is because the producers added a huge amount of unnecessary and useless scenes, that no one cares about, especially boring scenes of their workplace.
Really disappointing.
Conclusion:
If you want a good romance drama, skip this one. There are a lot of other better c-dramas.
