I only watched this drama to see Ji Chang Wook. As always he does a good job to portray the character who was frozen for 20 years and woke up just as handsome together with a female volunteer of experiment played by Won Jin-A. The chemistry between the two fairly good but but fail to hold it's passion consistently throughout especially during the last 3 episodes as Won Jin-A was frozen again and poor JCW had to wait another 3 years for her to awake.
After being frozen for 20 years and additional 3 years, surprisingly the heroine still not in a hurry to marry and want to experience more on developing her own self. Luckily JCW character is understanding, compromises and supports her dreams. Somehow, towards the end the mutual love and passion did not seem quite balanced. Happy ending, overall a drama one can watch if there is no other interesting dramas to watch. Strictly for fans of JCW advisable.
