Windy Mi Poong (2016)

Both dramas have a
- lawyer male lead
- three couple cast
- grandfather character looking for a child from which he has been separated for a long time
- slow burn main couple romance

Both are about a South Korean man and North Korean woman falling in love. Blow breeze is different in that the man is a lawyer and the woman defects from North Korea as a pose to Han Ji Won's character who was a soldier in South Korea on a joint mission and ends up falling in love with the then prince and who eventually becomes king.

Blow Breeze and Young Lady and Gentleman has the same writer so viewers will experience the same great beginning with a lovely story telling only to be overshadowed and nosedived by ridiculous parents and subplots.

Same style
