I would definitely recommend this to anyone who likes a bit of thriller, suspense, and crime-solving. The romance in this drama isn't really "officialized" but there are A LOT OF HINTS and very obvious ones as well.

Personally I love the male lead. He's extremely intelligent, gifted with a supreme eye for details, and is somewhat of an all-knowing person. He's humorous and has his own swag and charisma. He's not the usual cold and unfeeling, domineering male leads you would see most of the time in the dramas.

The female lead?... erhm... at the start, I did like the female lead, she's seen as a capable, likable, cheerful, rational female lead... but as the drama progress... the female lead seems to rub the wrong the vibe to me personally... like she kinda losses her good points and becomes the sort of female leads one would see in dramas... YES, stupidly naive, kind, reckless female leads... OMG... and a bit annoying as well. Idk, this is just my personal opinion. Though, there are times in the latter part of the drama whereby the female lead regains a bit of her IQ and her good points that were seen at the start of the drama. SO don't worry too much.

Spoiler Alert:
There's a twist as to who the main antagonist is... hehehe... I was personally surprised for the character was my second-favorite after the male lead. In the last few episodes of the drama, it seems to take a dramatic turn, like new characters are suddenly introduced... I don't really think it is necessary to include those characters, I mean if they want to include them, at least included them in the middle of the drama, not the end... like wth... and the way they were introduced was very abrupt... it was really bad, as pointed out by previous reviewers or commentators, it made the audience watching the drama feel like they missed not just one episode but many, many episodes... The ending was... I don't really like it. It was an open ending, goddamnit... like why?!!! Idk what happened to the production crew or whatnot but the latter few episodes as well as the ending was really bad and not to my liking and I think most people would've found it quite annoying as well.

My ranting:
I mean idk if there's going to be a season 2 or not... if there is I would definitely watch it. But, if there was, then I guess the open ending could be a great start for the second season but if there isn't... wth. Anyways, I would still recommend this drama, it's really good, just not a perfect drama, I mean there's no such thing as perfection isn't there? And regardless of my misgivings with the drama, I still rated it a 10.. because it's really an enjoyable watch!
