Honestly I've rewatched this show many many times, and this is another one of TVB's mystery dramas, but I always found those entertaining. This one uses a lot of science which is quite okay to watch the first time around, but I usually rewatch because I think the romance in this series is soooo good!! The casting is perfect as well, I think it's nice to see a smart, sensible role of Raymond for once and he and Tavia matches so well!! I love seeing them fall for each other in the beginning and then things get rocky for them but you see them grow from it through multiple time tests. I really recommend it!!
