It was a little confusing for me for a while. The multiple personality storyline I knew was coming but it came up quickly and I guess I wasn't expecting it or something. Not sure. Nevertheless, it was handled really well. There's a bit of suspension of disbelief regarding how the doctor who isn't a doctor yet gets to take care of this very sick man, but whatever, it works and I was sucked into it. Ji Sung

Ji Sung does a fantastic job acting the various other personalities. My heart was broken into a million pieces as he works through their origins and extinctions. Hwang Jung Eum carried a big load as well and she did it flawlessly. She was funny, competent and believable. Together they were on point emotionally and their chemistry was perfect.

Park Seo Joon supports the pair so well as the brother who knows more than is good for him and his sister. His struggles tore at my heartstrings almost more than the main couple. UGH. Don't make me cry. But cry I did. A lot...and I'm not really a crier. I was happy to shed tears for this one, though. Totally worth it.
