It is a tried and tested Cdrama Formula about Substitute Marriage one thing it differs from others I have watched is it's Ending. The Writer tried to tell a too big of a story in a shot drama and thus it became too fast paced. And the actors couldn't live up to the mark as well if the acting was better it would have gotten better rating.An actor with better acting in the Male Lead would have made the drama more enjoyable. All in all it was a okay filler drama but could've been better with a better Male lead and a little more time for the plot to develop.
