a great revenge drama, loveeee it. the prison setting and stay of execution was unique, breathe of fresh air, it makes me curious on how a doctor could take revenge to a high up person. the storyline is very interesting, especially with the characters keep changing side and the smart plan that was came up by the male lead. twist after twist I like a lot. I also like that they include psychological diagnosis too giving some in depth towards the medical part of the drama. As for the acting, it was great, Namkoong Min did a really great job in bringing his character to live. Anyways, love it.
