First of all this drama is slow- paced but after ep 3/4 u will be hooked, I assure you. Ji Sung‘s acting is too good to sleep on it and the music is put up perfect. Just give it a try and watch how Ji Sung acts as twins who are completely different from each other. I also have to mention how loveable the younger brother is. You will know early on who the enemy is but what’s more interesting is how u pray each and every second for the ML to not die. They are walking on a rope, so with just a finger snap someone could fall down.
Just emm… give it a chance and u won’t be disappointed. If it does disappoint u( which won’t happen), I will give u 5$ lol.
