The premise of this show talks about a first year neuropsychology doctor becoming the person physician for a guy suffering from Multiple Personality Disorder.

I found this show quite slow to start, the elements discussed in the premise don't actually start until about Episode 8 and for me that was when this drama actually started moving at a decent pace - I was close to abandoning it prior to that but kept going because the premise sounded good and I wanted to see if it could deliver. In short, it did ultimately and very well, you just have to push through that slow bit in the first few episodes.

A first for me - I just didn't gel with the Female Lead in this one, crying and screaming just didn't seem real, they felt like comedy equivalents put in non-comedy places. I am going to have to look up some more dramas with the same actress to see if this is a direction thing perhaps, it's unfair to judge based on a single performance. In all other respects I thought she was great though.

The Male Lead however shines brightly, showing various different characters through the different personalities with sufficient difference between them that it's almost instantly possible to see which character has taken to the fore purely from his performance. The highlight from a sheer comedy gold perspective has to be Ahn Yo-na and the antics of love-chasing Oh Ri-on, hilarious and a nice bit of light entertainment punctuating some of the heavier scenes.

It's a complex, perhaps convluted even, plot but it makes sense once it's unraveled.

Overall worth a watch, definitely, but you will need to push through the first few episodes until she moves in with Cha Do-Yhun before the plot starts moving at a good pace - and then it's easy easy watching all the way to the end.
