One of my all time favorite Korean dramas. I have re-watched this at least 5 times and have never been disappointed, it sits at my second favorite of all the dramas I have watched. This drama displays a very unique and worth praising story line and obstacles that are given to the leads in the drama. The female lead was always so insecure of herself, and went through a lot of harassment since she was younger. The only logical reason she thought she had left was to change herself by undergoing through a surgery. At first she was very satisfied with it and started fitting in, but as someone from the past she once knew and had feelings for had come to her university, her life was going to change. This is because he knows her secret from the past for what she once looked like. He is very popular in the school for his looks and is a cold male lead indeed. But he does not have interests for anything and comes to only care about the female lead from their chemistry. Much more challenges happen throughout the drama, when you go deep into the story, but this drama was definitely a cherished drama by its many viewers. Many surprises will happen throughout the story, and many obligations and objections will go throughout their relationship/love for each other. Once your very deep into the drama, the end will come with dark turns and complications. So have fun watching/binge watching. This drama is definitely worth it.
