The Best mystery drama I've seen in a LONG time! I marathoned it in 3 days, as soon as I watched the first episode I was hooked and could not pull myself away! I was constantly conflicted over who the real criminal was. I'd go from one suspect only to add another and another and another! I had at least 5+ suspects on my list and a few went on and off a couple of times lol If you are like me and love a good mystery, then this is one not to be missed! Cast: Yook Sung Jae as Officer Park Woo Jae was my personal favorite character - he was so eager, determined, nice, and wouldn't let go of his "detective instincts" ^^ He'd investigate things other detectives were brushing off with the help of his sunbae officer Han Yeong Sa whom I also really liked - two great officers/unofficial-detectives from a rural area who shined the most! Moon Geun Young as Han So Yoon was great in her role as the new teacher trying to figure out what brought her to Achiara. (not everyone likes her acting, but I do, I couldn't imagine another actress playing her role). Ohn Joo Wan was my second favorite character - I loved every scene of his. Choi Jae Woong as "the young agashi" was the most confusing and perplexing characters in this drama! Great acting! Park Eun Seok as Nam Gun Woo "the art teacher" another complex role - definitely going to keep my eye on this actor! Every actor did such a splendid job with their character - and I can't say much or I will unveil the mystery! Music: this is the first time I actually enjoyed the instrumental OST this much - it fit perfectly and still remains in my memory - usually instrumentals don't leave a lasting impression for me but this one did. I would definitely re-watch this drama again! Such a good drama! I'd recommend it to mystery lovers!
