Starting this review with a warning for anyone expecting this to be a romance drama, it is not. Yes, there is romance but somehow the overall feel is more of a melodrama. Fair Xing and Allen Ren did well. Fair Xing continues to show depth in acting. Allen did well even though the character he portrayed had a limited range of emotions. The second leads were okay along with the rest of the cast. I am not a fan of the story as I couldn't really get into the concept of a mechanical heart so I got bored sometimes and dragging on to 36 episodes did not help. Also, some blatant product placements were annoying. The ending, although a happy one, having a 3 year time jump to wrap things up was rushed for my taste. On the positive side, I absolutely loved the cinematography on this one. Shots were crisp and well framed. Locations were pretty. No annoying dubbing. The OST is nice. I admit being a bit disappointed with this drama but on my fault having unrealistic and high expectations coming from my enjoyment of My Little Happiness which is a different genre in my opinion. Overall, watch this if you don't mind melodrama.
