I quite enjoyed this, and it was even the best drama I've seen so far in SOME aspects. So let's dissect all my feelings I have about this:

PRO
- Ji Chan Wook is very charming and I loved looking at his face and listening to his voice. When he was wearing glasses and had his hair styled out of his face he was almost too good-looking and I kinda lost focus of what's going on. Should that be a con...?
- The villain in this was AMAZING. To me the actor gave the best performance, but also the script was just very solid. Super good writing throughout the whole crime/investigation portion of the show. Very solid arc for the villain as well.
- All the character relationships come to really satisfying conclusions. I was quite happy with where everybody ended up, especially in relation to each other.
- Very likable side characters. By the end I loved all of them, even the ones who were a little hard to digest in the beginning.

CON
- Bong Hui's personality swayed quite a lot from my initial impression of the character. Just the fact that she talks about s*x in a kdrama made me wanna see more of her. A female lead acknowleding that s*x exists?!!? Unbelievable. (Do I even have to censor s*x? I don't know what the guidelines are and don't want my review to get taken down, so, sorry if this looks silly to you.) Unfortunately she kinda turns into your standard fare female lead after a few episodes. Bubbly, easily upset, a bit childish and naive when it comes to romance. My main complain was kinda towards the end of the drama when Bong Hui and Ji Uk have more time to spend together and go on dates and such. Her body language around Ji Uk makes her seem very uncomfortable. I almost can't believe this was intentional. She leans away when he leans in, she takes a step back when he comes closer, she makes a really frightened face when he makes advances towards her... That's not the behavior of someone who's attracted to that person and it detracted from the believability of their relationship. Their steamy kiss that led to s*x also came kinda out of nowhere to me? They spend the whole day barely holding hands. What made them so h*rny??
Anyway, this might seem nitpicky, but this is really something I look for in romcoms, so, yeah, I'm gonna be nitpicky about it. I don't need steamy scenes or anything, but at least make me believe these people are attracted to each other for real for real.

In conclusion: Amazing villain who stole the show for me. I'm not a rewatcher, but I might even rewatch this eventually...

And that concludes my two cents.
