I just started watching this drama because I love Kim Soo Hyun's work. This drama is giving me such heartache that I have to stop and take a break from watching. It is heartbreaking to see what the character portrayed by Soo-Hyun is going thru. The heartbreak and emotions I feel while watching this drama is a testament to the spectacular performance of Soo-Hyun. Even though it is such a great performance I would rather see him smiling more than crying. I applaud him for his sensational performance. I will watch to the end and hope for a happy ending and seeing his beautiful smile.
