Still can't get over the ending........ This drama is just wow..... Literally was thinking all day what will happen next, what will happen next as it just increased our curiosity after every episode...... Yoona just nailed it.... It felt so natural with her acting skills, lee jong suk also nailed it, in jail he literally gives his all in those scenes and in the ending every scene was breathtaking.... Kim joo hun the best.... He as the villian in this series is my most fav character... Kwak dong yeon, yang kyung won, oh eui shik, etc everyone who has contributed in this series nailed their roles........... Now whoever has seen my review please go and watch it now because if you are not proper korean drama fan then this drama is for you.
