I didn't finish this drama and it's a pity. I am a fan of the Orion-Origin chemistry (the leads) in Kill Me Heal Me and was expecting a lot from this drama. Starting story is interesting and there is so much potential for the drama. However, the drama becomes really draggy at the middle/back portion and the only interesting thing left is the secret identities (no spoiler). I do appreciate the character developments but they somehow become stagnant and unimportant (again) at the back of the drama. Anyway, I was utterly disappointed by the leads and how the romance turned out to be that I just cannot continue. The chemistry is great and all good between the actors/actresses. I especially loved how the (rare) womance is displayed by the actresses. and honorable mention to Siwon for his great acting:) All in all, quite disappointed. Nonetheless, I still enjoyed the front part of the drama. Will continue to finish the drama when I have the time or urge to do it..
