Ok, I decided to watch this drama b/c of Lee Sang Woo when I saw him in A Warm Word drama - I immediately liked him. But to be honest, this drama was slightly disappointing...Why? b/c they showed the 2nd lead guy WAY more than they showed the lead guy, I don't know about anyone else but when they do that it really bothers me. It started off pretty interesting, but the fact that they pull the "amnesia" thing in this drama got really frustrating - most of the drama I was disappointed in the lead girl - how could you not see the great man standing by your side? She always seemed drawn to the 2nd lead - throughout the drama I was pitying the lead guy and hating on the lead girls dumbness. after she found out some things it started to pick up again - but when her memory comes back she practically throws everything in the dumpster and really hurts the lead guy - enough so that I wanted her to be Unhappy forever. However the drama did end nicely (after all that ridiculous revenge stuff got over with). If you can sit through all the frustrating things then I'd say a one time watch of this drama may not be so bad...but I wouldn't recommend a second watch. overall, I am glad I watched the drama (if only so my curiosity has be quenched).
