(It contains only a slight spoiler). At the beginning, the series introduces you to the life of the main woman character, who lives with the ability to hear when someone is lying. That would sometimes suit everyone but only sometimes. She hears the lies all the time. And this causes problems in the family, she basically isolates herself from other people and friends, except for the two who work for her. She cleverly builds a business on her skills and uncovers lies for clients as a so-called shaman. This job of hers brings fun scenes. However, a new inhabitant of the neighboring apartment intervenes in her life, who is mysterious and always wears a veil covering her face and avoids people. To her surprise, she discovers that he is not lying to her. But gradually it is revealed that her new neighbor is a publicly known person, a music composer who is hiding from the world because he was suspected of murder in the past. In the series, we also encounter the corruption of a policeman by a politician. And we have another policeman (a very nice actor), an ex-boyfriend of the main character, who doesn't like something about the main character. And it happens that both the protagonist and the policeman investigate the past and look for the real perpetrator. And as usual, the ex-boyfriend suspects the current one, and the current one suspects everyone, except the real one, because sometimes we don't see what's in front of us. Everything would be great. The main character, Kim So Hyun, is pleasant and the role suits her. Hwang Min Hyun was sometimes super mysterious, and confident, but sometimes reserved, and scared. I couldn't move a little in it. I liked him so much in the role of mysterious, charismatic, but self-confident with quick reflexes and with a sword behind his belt (yes, I guess I can't get rid of his fight scenes from Alchemy of Souls :D). The chemistry between the main characters is okay but I needed somehow more and what bothered me was that the creators did this again: after the main characters get close, the first kiss falls....and then they treat each other as if they are 15 years old and they look like as if nothing happened, or they are shy and it's embarrassing. Why do this with adults? oh ... for this, I'm lowering the rating, they could have grown up to this... but what I appreciate the most is Yun Ji On (the main character's best friend). I saw him for the first time in the series Tomorrow, where he impressed me so neutrally and I thought, hmm, quite an interesting actor... But here he wiped my eyes out. Brutal acting, and charisma, he looked so great there. Perfect. I was so captivated by him. Every movement, gesture, look, tone of voice, sentence ... everything was elaborate. I went through everything with him and I kept thinking to myself, how could someone live such a life and suffocate everything? What was it good for? This character in the series has led to many questions and controversies, and because of him, this series is worth watching.
