I have a serious love/hate relationship with the main character. Small character development and her lack of impact on the overall plot. But, its fresh and a different approach to the typical hero of all dramas. SACRIFICE being the main theme but approached differently from all characters is lovely just as its heartbreaking. Acting is top notch. I watched this because I saw the cast was impressive and they definitely delivered. Amazing acting. Impressive osts. One of the few dramas that deserve 10/10
