Its very very worth to watch. I described it as watching and interpreting a beautiful painting that says it all. Perfectly acted, executed, edited and directed. The actors gosh...as in 100% fitted to their roles. Take note they include books... that inspire and to give more deeper emotions in the dialogue. The moral lessons... the courtesy the relationships... we must all do and have. Watch this series its perfect! Its a never before seen acting of Park Bogum and a tremendous emotional acting of Song Hye Kyo. The romantic on screen chemistry brought the LONGEST BALCONY KISSSING SCENE for both actors in kdrama and the sweetest...there's the innocence...pure loving intentions...the emotions that is coming from their eyes. There's alot to learn from this kdrama. Kudos writers and director ! Iam having a hard time finding another one like this.😍😭 mixed emotions.... for the nth time watching since its first aired. How long?16 episodes but still watching...not getting tired...
