There are already plenty of reviews for this drama, so instead of an actual review, I'll just write some thoughts that may or may not ever be read. Just because. LOL

--Is it really really good acting, or do I actually, truly, hate the mom??? Also, I hate that she never understood that she was the cause of her son's moral deficiencies.

--The plot twist. I wasn't expecting a plot twist. How was I not expecting a plot twist?? I was truly surprised. And honestly, it was informational only....they would have been fine without it. But it did give some justification to the motive.

--I never did understand the relationship between Yu Ji Hyuk (ML) and Lee Suk Joon (Lawyer/HR). I got a sense that there was a familial relationship, but I was never sure.

--Yu Hee Yeon was adorable! It's nice to have a genuinely good character occasionally. Not to mention, intelligent and helpful, with no ulterior motives.

--Poor Baek Eun Ho. He was so clueless throughout the entire thing. I felt so sorry for him.

--Yu Ra's bodyguard/driver/secretary.....he looked so betrayed in the last episode. Not to mention his reluctance to murder people. His role was pivotal in saving some lives. I thought he deserved a better ending than to be left standing in the parking lot.
