Guess what?! I'm the unpopular opinion (again...). Anyway, "While you were sleeping" started so so strong, with beautiful cinematography and griping story, dreamy like. Unfortunately, the cinematography later on appeared here and there only, and I really, really wish that they had more of it, like Goblin. Another plus was the cast. Love the two leads, but Suzy wasn't at her best. Maybe it was her character that was kind of odd and annoying at some point, but it just didn't work. Not that her performance wasn't great, it just felt like the role wasn't for her... The love story and the couples chemistry, moreover, was okay and really good at first, but kind of felt weak towards the middle, picked up though towards the ending. In addition, the soundtrack was perfect! Really good indeed, Scarlet heart quality (you should check it out if you're interested in OSTs). Finally, the cases: they were interesting at first, but they got weaker and weaker, especially as the story focused on the couple rather than them. So, 5 out of 10, not too bad but not too good.

I didn't expect much on this drama at first, but watching this drama to 20 episode. It was surprisingly much better than expected. There was good funny scenes in drama that I LMAO a lot. The story was good, the best was humor of drama, that i didn't expect laugh a lot. And it was also romantic, but in artistic way, that asians dramas usually has.

series are ongoing so little i can put as a review here I am missing the LJS's superb acting I think after watching 4-7 episodes till so farstory plot is not so appealing to me I felt Kang Chul was the best version of LJS acting and I hear your voice was the pleasing story plotseeing Mr actor LJS's acting is really a treat though :)

It's really hard to surprise me with drama plots, because I've seen so many Korean, Japanesse drama series. Well...maybe it's possible. This story is unpredictable, realistic character relationships and the chemistry between the two main characters is undeniable. I would recommend it to everybody who likes mystery, detective, romance and little bit of sci-fi. And of course the actor Jong-Suk Lee, have you ever seen him in a bad drama? Definitely, not! I think his acting skills makes this drama so watchable. As I said, this drama is "excellent without a doubt"
