I have just finished watching Crash Landing On You for the second time... And mind you this is my first ever K-drama, and I fell in love with this series!!
The story is a cliche of a rich spoilt girl meets a humble, down-to-earth boy and both of their life changes forever. But the backdrop of the cultural differences between North & South Korea, the political storyline, and the small moments beautifully portrayed in th show is what makes this series stand out! Watch it for Se-ri to fall in love with Jeong Heok... Watch it for the action packed scenes of Jeong Heok beating 20 villians at once... And watch it for the beautiful landscapes of Switzerland they have showcased.
No matter what your reason is, if you are looking to start a K-series, start with this one... And you will never regret it for a moment!
