Long time since I've seen Rain in any dramas so I forgot how charming and funny he could be. I certainly didn't expect to really love this drama which was basically a medical Rattatoulle drama with coma ghost instead of a rat.

Rain is really so lovable as the genius cardiothorasic surgeon Cha Youngmin. He really embodied the character description of being like a viper on the outside but actually a softie inside. Kim Beom was unexpectedly adorable as the cute chaebol resident doctor Go Seungtak. I totally didn't expect to be endeared to the childish Seungtak who seemed out of place at a hospital when he didn't actually have any skill besides being studious.

Rain and Kim Beom really did well in potraying the mentor-rookie relationship between Youngmin and Seungtak, even when this relationship didn't actually start on the right foot. Between a kind-hearted doctor who had worked hard to achieve great skill that could even be called genius yet ended up becoming jaded due to some twists in life and a resident whose merits was only on his vast knowledge he learnt but never did any surgery work due to the trauma from his childhood as well as his ability to see spirit causing him to be scared of doing surgeties, it was interesting to see how their life started to change when the two of them meet and forced to work together. It was interesting to see how Youngmin start to recover his old self and to see Seungtak becoming more determined to overcome his fears and become a real doctor.

That said, Uee and Son Na Eun were great as the romantic interest of both the male leads respectively. As much as most of Youngmin-Sejin scenes are quite melodramatic, there are still some cute parts in between and Sejin does still have parts where she had to remain strong. The same can be said about Soojung, and I love all the comical and heartwarning interactions between her and Seungtak.

While there weren't much romance in the drama, I love the fact that the actors were still able to subtly bring out those elements and show that these characters really do love each other. Like as much as we barely see Youngmin and Sejin interact normally aside from the flashbacks, we can see how both of them struggle with their sorrows as Sejin tried to find ways to revive Youngmin and how Youngmin couldn't do anything but watch her suffer because of him. There's really a lot of melodrama in Youngmin-Sejin pairing that it make sense why Youngmin would've wanted to reset that and made it a romcom. Soojung and Seungtak pairing was also cute seeing how the pair tend to support each other in their own way, which made it even more interesting when we get more revelations on their relationship beyond just being childhood friends.

Tae Inho's character reminded me about another similar character he played in Descendants of the Sun, but hey, every medical drama do need its villain and he seemed a perfect fit. Gotta say it was interesting to see Sungwon's relationship with Seungtak and compare it with Youngmin.

Sung Dongil was amazing as the resident ghost that still haunts the hospital and still occasionally helped out with things at the hospital. It was really heartwarming to see Tess calmly watching over the living and those stuck in limbo for 20 years at the hospital, even more once you find out about his real identity. Honestly, with every episode we receive tit bits about Tess's true identity and I just can't stop feeling amazed at how the little pieces of the puzzle just fits together.

As much as the drama was medical and supernatural in nature, one can't deny that it was also a family drama. This drama was really heartwarming as it reminds us to be kind to people as well as more thoughfull to others. I wasn't expecting to be drawn towards the stories about the patients and doctors beside the whole premise about a ghost doctor who continued to save people by possessing a living person. It was really fun watching this drama from the start till the end.
