I really liked this drama and I generally am super meh about medical dramas. It wasn't exceptional, but it was interesting and kept me entertained and excited for the next episode. The lead actor brings a lot of intelligence to every role he does, and this role was no exception. He plays a man with limited emotional range and empathy ostensibly because of a failed brain operation as a child. The actor does a decent job depicting an emotionally stunted character.

Unfortunately, toward the end things got pretty sloppy and I really didn't get the plot twist with his dad or why it was necessary. From the beginning I felt like his dad was a bad guy, the actor they picked just LOOKS like an evil guy. Adding a weird redemption arc and confusing trauma sub-plot really didn't advance the plot in any satisfying way, it just basically confused things. Maybe that was because the twist was introduced/handled so casually that you felt like you needed to rewind to see if you'd missed something somewhere.

I did like the interaction between the two leads and the male lead did a really great job never dropping the plot thread of his disability. I liked that they didn't heal him with love at the end like every other mental illness Kdrama. I liked that he retained his core defect and embraced it and worked with it instead of against it by the end. But mostly...I just like Jang Hyuk as an actor XD.

Overall, I wouldn't rewatch this show because there isn't anything compelling enough to interest me. Everything was decent and satisfying, but it's a one-and-done sort of story.
