Scarlet Heart Ryeo might only have 11% ratings in its country but the international fans love this drama so much. Its OST is one of the best and the cast is perfect (well for my POV). IU's acting can be improved but hands up (and feet too) for Lee Joon Gi and Hong Jong Hyun. Kang Ha Neul is awesome too. I love to hate and love him too at the same time. I hope they added the tragedy category earlier so I can prepare my poor heart with its ending. This will make you feel so much emotions. Love, hate, anger, sorrow, grief and hope. Im constantly at the edge of my seat. I can say that this drama is worthy to be rewached! Ready your tissue.
