If you're looking for a decent mystery with a side of romance, this may be fit to your tastes! Story The synopsis of this drama was interesting and somewhat uncommon; a girl who can see ghosts wakes up from her coma teams up with her co-worker to solve problems for the dead; however an underlying mystery that was forgotten resurfaces as they try to find out what really happened 6 years ago. The first few episodes was a thriller! It had so much potential as it got me hooked onto this drama within a heartbeat; the storyline and plot were really well written overall; however the downside was that this drama felt like it started to get boring and it was dragged out nearing the middle/end. I a a huge fan of mysteries and the 'frightening ghosts' concept intrigued me and i was thrilled that the first few episodes had responded to my wants; however as the story goes on, it seemed that the concept of ghosts appearing was dying down; until eventually there weren't any more new ghosts appearing. It became disappointing that the villains and ghosts were not evil nor interesting enough which made me quite sad at the plain characters. Acting The cast were amazing; as it frustrated me that I wanted to root for the dead boyfriend and the girl as much as the real main love interest. I wanted Cha Gun Woo (Taecyeon) to be with Shi On (So Yi Hyun), however i found that Shi On had a much more amazing chemistry with the dead boyfriend. Although I did find Gun Woo and Shi On incompatible at times, i forgave that as their portrayal of their characters were amazing. Yang Shi On was a believable character; as someone who had just woken from a coma, her confused and shocked character was believable. Cha Gun Woo was like a little kid; amusing to watch his character interact with everyone else. Lee Hyun Joon (portrayed by Kim Jae Wook) was surprisingly one of the most beloved and pitied character despite being silent and not talking for about 80% of the drama, his situation and actions for Shi On were enough to make me love him all the more! Music Can't say much about the music, it wasn't horrible but it wasn't amazing either; but it was pretty decent. Rewatch Value I can't say whether i would watch the entire drama once again since there were many parts that i found too slow, however I would definitely rewatch the first few episodes since they were the best! Conclusion? However, despite the lack of a 'real' thriller mystery drama i was hoping for, Who Are You is a decent drama that deserves a watch as it would definitely make you hooked and connect with the characters.
