I quite enjoyed this. Even if it got the "supernatural" element to it with FL hearing lies, it doesn't spin off into lots of superstitious stuff, but kept it at that. The balance between romance and suspense is good, and what drives the story forward.

Brief synopsis:
The female protagonist, Mok Sol Hee, is a rather lonely soul with a complicated relationship with her mother. MSH can detect lies by listening to people, and makes a living as a shaman offering her services. The ML, Kim Do Ha, is a successful music composer who hides his identity due to a murder allegation in his past. Their lives cross paths, and as they get to know each other and unconsciously help each other "heal", his past might come back to haunt him.

The story has an original twist to it, which I appreciated. Overall the flow could have been a bit smoother; there was some unnecessary derailments, although not huge ones.

Casting is good, and I mainly liked all the actors in their roles.

Hwang Min Hyun (1st ML) kind of reminds me of Cha Eun Woo sometimes. He gives a good performance as Kim Do Ha, however I feel sometimes his performance could have been a little bit stronger. He has a lot of good moments too, though, don't get me wrong!
Kim So Hyun (FL) is "her usual self" I would say. This isn't a remarkable performance, and I kind of wish her character had been a little stronger/fiercer in some aspects, so she could try to shine a bit more. They do have some cute moments together.

I enjoyed watching both Seo Ji Hoon (2nd ML) as Lee Kang Min (police), and Yun Ji On in the role of Jo Deuk Chan.

To sum up:
I liked the kind of original twist on the story, but it could have been kept a bit tidier without some of the sidetracks. It was enjoyable and rather easy to watch, but I don't think I will watch it again.
