The characters crisscrossed time into the future and back to the past so many times that I lost track. However, it is an interesting drama. I followed it through continuously and completed watching it across three days while recovering from a flu.

Two lovers from different time periods were star crossed and their shared memories were eventually erased. The drama cleverly kept its audience guessing the identity of two individuals- the missing boyfriend and the real killer, and wondering whether the killer could be stopped on time to save the lead lady.

The main actress Ko Chia Yen was excellent. She acted two completely different characters very convincingly - a timid depressed young teenager with an inferior complex and a confident university student who grew up very assertive.

The actors and actresses were good looking. The main cast acted their parts well. Some of the insignificant minor characters were not so convincing; however their less than a minute duration parts did not impact the overall drama. The backdrops were appropriate for the scenes.

The pace of the story was quite slow, so you have got to be patient. I nearly wanted to skip to the last episode.

As for the music, it's just that one piece 'Last Dance' and that's about all.

The main negative is the ending did not flow well. Suddenly, the main couple was on a bike appearing from nowhere - how they met again was not explained - if it was from the time when the female lead was a child, it would be very tacky.

If I were the writer, I would let them meet in the future with a role reversal - with Li Zi Wei returning from Canada, walking into a cafe and ordering his coffee. The waitress whose back was toward him, answered in affirmative, prepared his coffee and turned to hand him his coffee. Their eyes met, they found each other very familar, stared and asked each other simultaneously 'Have we met before?'

Overall I would highly recommend this drama.
