What is the first impression of this series? Dynamic scenes, a promising plot and a cool hero, of course. He’s the type many girls like: good mannered, with a memory loss, slightly awkward with girls, but not a mush-head. He will take the initiative into his own hands, and protect his girlfriend even if she’s a police officer and is supposed to be able to take care of herself. It was also fun to watch this series together with my family ‘cause there were some occasional flaws such as medically strange actions and weird technical equipment and everybody’s been commenting on it.

Liu Zi Guang is just lovely. Life has given him a chance that he would have never had if not for those eight years. Not only he has learned how to fight, he has returned not as an undecided schoolboy but as a young man desperately looking for his place in this world. And this is just the way he creates this place for himself. If he spent his youth happily, he would not have to seek answers: with his inner compass, he would always know what was right. But the dark side of his past raises his doubts and makes him a hero.

I really enjoyed the scenes when Liu Zi Guang met his sort of madness and despair, breaking through his memories - not entirely by accident, but in order to remember something else and defend himself. The way William Chan shows Liu Zi Guang’s despair when he realizes who he really was is just great. The audience, however, already knows the truth about the main character’s past, so I highly recommend to start watching from the third episode no matter how emotional the first two are (you can watch them afterwards, but do spare yourself a bit of intrigue).

The main female character is nice, you can sympathize her at times. She is brave, and weak, and smart, and too impulsive. She is desperate to claim a dangerous job, proving to everyone that she can handle it. But the more the plot develops the more she is shown as a daughter, as a girl in love - and the image of the tough and rude Hu Rong evaporates, showing a vulnerable young woman. The story would be more interesting without this sentimental pliability. After all, undercover relationship is risky and interesting but the plot drags too much at that part, showing the heroine’s immaturity and putting the whole mission under an unnecessary risk. Hu Rong’s always making her father give her a chance to participate in the missions is rather irritating. And of course, it's hard to forgive her going to the base without a bulletproof vest, I mean, where’s the logic here? It was so easy to come prepared. She’s a police officer, not a school girl! But she is an interesting mirror for Liu Zi Guang. That’s very common for such kind of the stories that the two end up as a couple but still nice to watch.

I also liked Officer Han. He was the third person in a love triangle, but he deserved Hu Rong no less than Zi Guang did. Interestingly, Han's sincere affection for both Hu Rong and Zi Guang seems not a plot flaw but a realistic life twist, although a typical rival would prefer to get rid of Zi Guang when he had a chance. Surely my favourite character after Zi Guang, brave and smart. (What would the police do without him? I mean, they don’t seem too quick.)

Finally, the villain is fine. All other don’t seem too dangerous or witty, though. But mister Nie has been plotting all this time. His observations and predictions are quite accurate. Still, his kind of fondness of Zi Guang is kinda strange even if they are sworn brothers. Why be so shocked by Zi Guang’s possible betrayal if you are ready to betray him as well? I wish they had shown us more of Zi Guang’s past in short bright flashbacks just to explain why Nie is so attached to him.

In general, the series went even deeper into my heart than it seemed. I fell in love with its music, too. The combination of characters and plot conflicts also seem appealing for me. I just wish it was a bit darker, without so much romance.
