The casting was all star great I loved it. I am big fan of Yoon Eun-Hye who plays Na Mi-Rae, and I always like to see Jung Yong-Hwa acting in almost anything he plays Park Se-Joo. The new actor for was Lee Dong-Gun Kim Shin who is a new anchor/journalist. I find the whole story to be pretty fun to watch, since there is time travel involved. It has comedy, romance and of course it's a love triangle. I felt they didn't wrap up the ending well which is why it's drama I wouldn't rewatch because I felt they sped up this drama just to get to another drama was more important. This drama aired close to the time " The heirs" was airing as well. It was actually more enjoyable to watch than "the heirs." Unfortunately it didn't end the way I had hope with some real closure to what happens to the couples if they worked out or not there is a hint how it worked out about a child they had together, but still it wasn't good enough BOO!
