At first it took me few days to start this drama due to summary... Sister and brother thing pinched me a little but then I thought about Lee dong wool and I realized he is a gentleman and in all his dramas he maintained dignity and never go over board to show his acting skills like others... I guess I made best decision to watch this drama... Acting and plot compliment each other... Both the main lead are amazing... Intensity of dong made me crazy... He cried, he was heart broken, he was evil, he was a bad guy but still he managed to blew my mind away... How it feels when your parents are your enemies and you know that your life is on risk due to them and how it feels when a parent realized in their ignorance they almost killed the child they wanted to alive for so long and waited for their whole life.... It is not easy to handle such situation but dong's expressions and his dialogue delivery made you feel at ease even after such chaos... He loved a woman who suffered hell due to him but she never gave up on him even after when he decided to left her alone... A promise that they made once kept them together and a string that attach to their heart gave them courage... A mother's hatred to love and a guy's rage to passion is all we need... When a woman decides to love him and ready to sacrifice all for him, he took all the responsibility to protect that woman... A drama that you can watch once a year every year....
