The story/cast/acting/music is good but the one thing that I notice is why kim hee a is the main character when she is barely in the scenes and shes barely interact with the mc until the last 3-4 episodes. This why upsetting me! why? Because if your a true k drama lover you will search the rating , cast and story of the k drama you want to watch if it is worth it to watch and i was angry because i was expecting more scenes of kim hee a because she was a MAIN CHARACTER but she is barely interact just like what happen in the ending they ending up with each other just like what i want but she was barely scene with the mc. Kim yuri was in the supp role but she was in the scenes most of the time. The show was hype and im eager to watch it despite of my time because i was hype from episode 1- 10 then the hype will down from 11 - 16 eps.

But is was a good revenge story though the time travel did not explain very well.
