I just finished this drama. Seriously, this drama was such a pleasant surprise for me. I never knew I would enjoyed it this much. I'm a sucker when it came to horror-comedy-romance-supernatural theme. That's what convinced me to watch this drama at the first place despite I'm not into both main lead. Here are my thoughts of this drama : Story : The main story is nothing new even most of time was full of cliche but I loved the way it's being directed and how both the main plot and the subplot complement each other. It was perfectly balanced and there's nothing to complain about. I never get bored while watching it. This drama also has subtleness in every scene thus make the story has more depth despite having a light theme. Furthermore, I also loved the fact that each of the character has it own importance in the story as none of the side character get left behind. About the ghost,some of them were really scary combined with the CGI and sound effect. Acting/ Cast : As I mention above, I'm not into the main cast. I found Taekyeon's acting to be average at best in Who Are You. Here, I can see there's a lot of improvement in his performance especially in later episodes. Maybe because he's paired up with Kim So Hyun who's acting is a lot better than him . Together they help each other thus resulting in believable acting and top-notch chemistry despite the age difference. I also enjoyed and had a good laugh while watching our comedy duo which provide comic relief in this drama. Music : It flows well with the story. The sound was pleasant to my ear. Maybe I'll download them later and add them into my KDrama OST folder. Rewatch value : Don't bother with this rating as I rarely rewatch a drama even my favourite one. Overally, I rated this drama 8/10. I recommend you to watch this drama if you get tired of melodrama at the moment and want a lighter one, if you're a sucker for horromance as me or if you want to watch something to pass out time. Give it a go as you might like it like me.
