Well, I was pleasantly surprised by how I liked this. It was very fluffy but not overly sweet for me. Seo Kang Joon was amazing in this one! For him to create such a big difference between Robot Nam Shin and Human Nam Shin is just amazing!!! I absolutely loved the parts where he faced himself head on. So Bong on the other hand, I'm sorry but I mostly disliked her here. I thought that being a female bodyguard would be empowering, but in the end, she wasn't even able to show her skill as one. She and Nam Shin had a good chemistry though, so I'll give her that.

Next, I want to mention as well the amazing acting of Yoo Oh Sung. He did a stellar job as the antagonist, and really really got into my nerves as a bad guy. The faces of annoyance he makes is just so fitting of his character!

Lastly, I want to mention my favorite character of all here: Ji Yeong Hoon. Ngl I've been in love w Lee Joon Hyuk already before this so there's quite the bias but his role here is basically wiping everyone's butts after they poop, I am serious here hahausksks Anyway, he deserves what he got after all he's been through! And that's actually the thing I liked the most about this drama.

On the other hand, I strongly believe that human Nam Shin doesn't deserve any redemption. The fact that he had a happy ending pissed me off, because they really just forgot that he almost killed 2 people? Like.. okay I understand his actions of rebellion toward his grandfather and all the hatred inside him, but many character in the series warned him to not go that far, and yet he still did. He deserves jail time in my opinion, and thats that.

I was surprised to see this drama had a lot of OSTs, unfortunately I did not pay attention to it that much and I felt like only a few stood out. I did, however, listen to the full OST playlist and the songs are good.

One last thing, I couldn't help but compare this to Absolute Boyfriend, which I really liked when I was younger. I was afraid of how the ending would be because of that, and yeah the interactions between robot Nam Shin and So Bong just reminded me so much of Absolute Boyfriend aksksks

All in all, good drama, kinda predictable but with the stellar acting chops and chemistry it's easier to overcome what shortcomings I have of it. Well, except that I still strongly believe that human Nam Shin deserved to be in jail, if he did, I would probably rate this a little higher.
