Ok.. finished this drama in 3days.. among super awesome c-drama! my feedback:

1. Storyline : 10/10

Very fresh storyline for timetravel genre. I normally hate crime/investigation genre, but love time travel so much. The storyline is very engaging and the different crime cases they tried to solve were actually interelated to each other. So feedback from others saying getting boring because not focusing on character development and too many cases are not true unless u watch pass ep10. You have to watch more to know the value.

Typical c-drama always dragging and focusing on too many extra couples & their side stories. This is not the case for this drama! Too many plot twist that made this drama super interesting & engaging. You really cannot expect how it ended LoLz.. XD

And typically for any drama (k/c-drama) when the main couple finally together, the plot start to decline & there r many dramas that i cannot force myself to continue after certain episodes. Not like this drama, once they started to confess to each other, another plot twist happening. Very² briliant screenwriter. I truly second to make this into k-drama like mentioned by other user!

2. Acting: 9/10

Both actor/actress r handsome/cute. Their chemistry started to improve at later episodes, which is good character development.

Really fun to watch the actor playing two different roles portraying different charisma/attitude. Many cute & funny scenes that worth rewatching. The switch between two characters (future & old lawyer) also very smooth and we can really feel two different entity, like twin with same memory..

Overall, please watch this! Especially to YOU, TIMETRAVEL FAN OUTHERE! Definitely worth every seconds of your time...

Definitely will rewatch this in future..
