This is such an amazing drama, I give it a solid 10. Main actor Zo In-Sung is so gorgeous, so cool! I fell in love with him in Winter When The Wind Blows, and he did not disappoint in this drama either. Not only good looking, but incredibly good actor, either playing it cool or showing incredible emotions. Female lead, Kong_Hyo-Jin, ranks one of my top favorite Korean actress. Loved her quirkiness in Master's Sun, love her feistiness in this drama as well. Chemistry & romance off the charts with this drama!!! What a great couple. Supporitng cast also really fun to watch. While learning a lot about mental illness, the drama did not depress me. Such a well done drama, I highly recommend. Rewatch value: 10, Feel Good Value at the End: 10+++.
