I was having quite a low expectation as I wasn't really keen of watching investigating kind of drama as it burns up my brain cells hahaha
BUT! This is really an exception of an investigating kind of drama that I LOVE!!
Wasn't giving it a full 10/10 just mainly because I think some parts of the production could have been better, such as:
1. Their water scenes filming
2. Some parts of the investigation got logical problem which doesn't make sense
3. Second main lead storyline was quite awkward and draggy

However, the 9.5 for this show GOES TO THE BOTH MAIN LEADS + THE BIG VILLAIN of the show!!!
Their acting just made the whole show up to the point, which makes the rest of the show SHINES :)
The main leads are pretty cute together and their interaction are very natural with very detailed expression! The big villain, I had never ever once felt so fuming when I saw the villain because I know they are acting, but WOW this actor just made me feel like smashing my phone when I was watching hahaha! Such an impressive acting and also a great character development!

For this drama, don't be too serious on the investigation parts, it definitely not flawless but in my opinion, it was not too bad too. But of course, if you also enjoy romance story, you will definitely enjoy this!
