This is from my view of the show and my opinion. Some may agree, some may not... This drama begun last year but since it was completed this year, I'm counting it as a (2015) drama. This drama is the most highly addictive drama so far, this year. An excellent drama at that too~ I usually tend to not keep up with currently airing dramas for some reason. I'm either a few episodes behind or I just wait until it's completed to marathon the rest. Not this drama. NOPE! I kept up with every single episode, every painful and long-awaited week and it was worth it! (You guys who have not watched this yet won't have to wait painfully like I did, you can just marathon the whole thing.) xP The overall plot was cleverly well-done in nearly all of the crucial, sweet, and fun moments. I had high expectations because Park Min Young (Chae Yeong Shin) and Ji Chang Wook (Healer/Seo Jung Hoo) but they completely exceeded those expectations in every way. Their interactions and chemistry were second to none, perfectly put together in fun, silly, casual, dangerous, and romantic/cute moments. I'm glad it didn't focus on the romantic aspect a lot like how most dramas would. I loved that. PMY did her role very well. It was believable and adorably cute~ Ji Chang Wook.... dear god! Don't get me started on this guy. He is such a bias wrecker! (^u^)~ He's one amazing actor. I noticed in most of his scenes, he uses his eyes to act as well. So brilliant! I loved every single episode/scene with him whether he was was with Yeong Shin or not. He made me laugh, cry, and scream... Hahaha xD Yes, SCREAM!!! His character was complicated but when you watch, you'll understand why~ It wasn't just them who made the drama fun to watch. The supporting casts too~ Yoo Ji Tae (Kim Moon Ho) || Park Sang Won (Kim Moon Shik) || Do Ji Won who played CYS's mom || Kim Mi Kyung (Min Ja/ajumma), Oh Gwang Rok (Healer's Teacher), even Park Sang Myeon (Chae Yeong's dad) made this drama extremely awesome to watch! Out of all the supporting casts, Kim Mi Kyung was the best for me. Hahahaha xD That woman killed me. She played her part so freaking hilariously badass! xD Lmfaooo xD I loved her! xD Quite memorable characters! The OST was just perfect! Every song fits perfectly with every scene. Even the english songs too. I already downloaded most of the songs! Haha! xD The instrumentals sounds so beautiful, even Ji Chang Wook released a single. OMG! When you hear his voice, you will immediately have an eargasm! The entire team did a fantastic job on this drama. It was well written and well directed. I highly recommend this drama! I wish it didn't end, but I'm definitely going to watch it again after I download every single episode! :D If action/thrillers with some drama and romance in the midst of all that is your type of drama, then you won't be disappointed one bit. I certainly wasn't. Give it a try! ^^
