The show revolves around life and love mostly and Kim Woo Bin played a very significant role in attracting the audience with his genuine acting skills. He did a great job along with Suzy. The drama made me cry a lot due to its tragic ending in the last two episodes but it's a must watch drama. It teaches you how loving someone can make you a better person in life and two correct our wrongs. It's a very heart warming story . Even though I knew that ending would be tragic from before, I cried like there's no tomorrow. And mind you I don't cry so easily over a romantic drama easily. The actors performed very well and it almost felt real to me. The OST is also the best.
