Overall I did enjoy this drama. The 4 lives broke the story up and kept me interested. The ML acting was stiff and awkward, he did not portray any emotions at all and had the same expression throughout the whole drama. FL was good, each time she was reborn there were subtle differences. I didn't particularly enjoy their story and didn't see how and why the ML fell so hard for that he risked his life over and over again for her. The stars of the show were the 2nd couple and their love story. Both played their parts well and I found myself skipping to their scenes.
