“If you love someone… that means you surrender – you lost. In other words, if you love someone then you believe whatever he tells you” -Heo Joon Jae-
The Legend of the Blue Sea was the first Korean drama that caught my attention. I wasn’t a fan of any Korean dramas before not even until I got a job from a Korean employer. I procrastinated watching this drama for no reason. To my surprised, it left me hollow and somber after watching it. It was a total package of fantasy, romance, comedy and sorrow and the cast was well ensemble that you might end up loving the second lead just like me. I was talking about Tae Oh (Shin Won-Ho) by the way and oh not to mention the lead cast Heo Joon-Jae (Lee Min-Ho) and Sim Chung (Gianna Jun/Jun Ji Hyun) who were both superb. The cast was one of the many reasons why I watched this drama twice in a row. And the plot? Yeah..it was totally amazing. I also loved seeing cameo roles of great actors in the series.
