This might be lengthy but I just want to share with you why I liked this a lot.

Usually I’m a rom-com person, will stray to a good law story (Suits) or political (Designated Survivor) once in a while but I haven’t in a bit. I saw the poster of this one, liked the looks of the leads, read the synopsis, twins, detective work, sounded interesting, started 1st episode and after three days not straying, just finished and very satisfied.

This show is about really good police investigative, forensics mystery work and it’s very riveting and intriguing. Dedicated to the core are its cast who never seems to stop working nor have a life beyond the uniform. For that you are very tuned into the mystery episode after episode with little rest to your imagination and emotions. The mysteries relate directly to the main people of the story which is why you’re deeply involved. You love them and hate them. Martial arts skills are great in the fight scenes and hands down applause for the training obviously put into this work. Though it’s not the focus, yet, the warm and tender relationship of the leads adds the flavor to this. Their romance is just beautiful with the maturity you crave in the eye candy idols cast dramas. Kisses are sweet and no big eye surprises or stone bodied hands glued to side either. Kisses are as it should be…clingy, returned, with warm hugs. Lol. Sorry but I’m so over the other unrealistic ones so was very satisfied in the sweet moments of this one.

The cast are all new to me but I’m gonna give them a shout out.

Bosco Wong dual plays twins Beichen and Beishen. Both have love interests so lucky him, he’s intimate with two beautiful women..haha. He’s so poised and dedicated to his work as a medical examiner that his character is strengthened by his intelligence and raw honesty, as he really needed to be to keep the woman he loved.

Julia Ye Qing plays Gu Chu, fellow medical examiner and love interest of Beichen. Beautiful and also poised, I love her facial expressions appropriately portraying her emotions. Her best yet was at the most, and I mean most painful moment of her character life. She’s great.

Gu Gao Wei is Capt Luo. This guy is absolutely professional in his character field. He’s handsome and enigmatic and also a poised leader. I researched him and found this is his first main lead role and he nails it. I would love to see him in another lead role where he gets the girl.

Liu Xian Da is Guo Chao, partner of Capt Luo. He’s reckless because he’s eager to be a good cop to catch the bad guys. I feel like he grew so much in the series and I can’t decide if it’s the character growth or actor growth. Handsome and naive, he grows to be a very resourceful cop.

The two antagonists are so good too. I mean the evil look, demeanor was perfect. Everyone on the team were good and big clap to them all. As to the ending? You’ll find closure I think.

I don’t know how they determine the popularity of shows and it looks like this isn’t favored. It’s seriously good though and if you feel you need a divert from other genres, give this one a go. I believe you will like it a lot. My overall opinion is a 9.5, low rewatch value because it’s no longer a mystery. Try it.

this drama caught my attention in the first episode. Some people may not like this ki9nd of drama, but if it doesn't grab me in the first episode just may as well forget it. these people did a fantastic job, most of the time at the edge of my seat. whoever the writer is, he/she did a great job. hey I even had questions, how are they related, I won't put my other questions down then it will give it away. Like twists & turns like this! as far as the cast, they were great, hope to see more of them in the future!!
