I found out about this drama recently and fell in love with it immediately, however, while I was watching I noticed that most episodes went by very slowly which made it somewhat boring to watch and just felt like a drag. Would've been better if it ended on episodes 8-10.

I found the characters okay, I feel like Yook Dong Sik would've had so much potential if he teamed up with Seo In Woo and didn't act like a total dimwit most of the time... There were times when I just couldn't bear watching Yook Dong Sik at all due to all the idiotic stuff he kept doing.

I found Bo Kyung a really smart and intelligent character but there were times when she would take so long to notice an important piece of information that could've saved her and the viewer SO much time, and watching her going back and forth with all the investigations over and over again made me really tired and disinterested sometimes.

I loved Seo In Woo's character, he was absolutely perfect from top to bottom. When he found out that Yook Dong Sik had his diary in episode 4 I knew that if he wanted to he could've ended him right away instead of just messing around and creating some long plan for 12 episodes straight. I feel like he would've been better off as the MC instead of Yook Dong Sik for several reasons.

In my opinion, this drama did a semi-good job of balancing thriller and comedy together. I found the jokes very funny but there were a lot of times when a scene could be dark and have a lot of suspense but then would get absolutely ruined by some joke. Like I'm on the edge of my seat waiting for something interesting to happen and BOOM a joke comes and destroys the whole moment
Overall I really liked it, and would definitely recommend it to other people !! would've given it a 9 if it wasn't for all the jokes and long meaningless scenes.
