The major fault of this series was the story about the main leads in the first 20 ep, was not engaging enough coupled with other things (chemistry, acting) that made the viewers ran away after the the first week. The messy storyline in the second half was mainly due to the desperate attempts by the writer to save the rating. Admit it or not, the first half of this drama was the cause of the downfall of KBS weekender, it's unfortunate because it got the decent start with 20% rating.

Anyway, mainly watched for Kim So eun, despite of messy storyline it's so nice to see her screentime increased in the second half even though the writing was bad. Unfortunately she ended up as the punching bag for the female lead's fans who were not satisfied with her screentime and with both her and Kim Seung soo also got the Best Couple award instead of the main couple ?

Rooted for Im Ju hwan to get his main lead role after Ugly Alert but this was just not it, although his performance actually stood out in the second half.

Lastly, won't really recommend this except if you are really a fan of any of four leads
