Psychopath's Diary is humorous and at the same time, suspenseful along with the best performances. I saw a short clip of this drama a few months ago and I knew it, this is what exactly I'm finding in a drama. And here are the things I enjoyed the most.

1. Yook Dong-shik ( His emotions were on point, I feel what the character felt. Even though this is the first drama I've watched from Yoon Shi Yoon, he has become my fav actor now )
2. Unnecessary Dramatic background music ( I love it every time, that one whistle music played, it was hilarious and matched perfectly with the plot )
3. The Side Characters ( Every single actors done a great job, especially Park Sunghoon. His acting was amazing that I wanted to slapped him )

Overall this is a 10/10 for me, I loved, LOVED it! And gonna be exploring more Dark-Comedy genre. ( Ngl, ML is a little too dumb at some point, but that's what makes the drama alive )
