Best drama of 2015. At first, I started the drama because I haven't seen a drama that had the two main leads in it. I mean, I tried Secret, but I didn't manage to finish. Though, I loved them separately in Protect the Boss and Can You Hear My Heart? Story: Overall the entire plot was great! I only have a few critics about the ending. I felt that 20 episodes wasn't enough for this drama to unfold. The last two episodes was rushed and it seemed that the production just had to pack everything in. However, the scripts were beautifully written and the actors did an amazing job with presenting what the writers had wanted. Acting: Jisung deserves all the awards that comes his way at the year end drama awards, why? Not only did he take on seven different roles, he was able to make me cry throughout the drama. Jungeum was great, but honestly in some scenes her acting was awkward. I feel that Seojoon will be nominated for best supporting role and hopefully he will win them. Then again, for this I'd like to focus heavily on Jisung's acting. No words can describe how amazing he portrayed a man living with DID. They all did an amazing job with presenting what the writers had wanted when making this story plot. My heart ached when they ached and loved when they loved. Is that weird? Props to this amazing cast. One of my favorite casts ever. Music: Loved the two main songs that were played throughout the drama. Let's just say the "cool" rap song and the sad song by Myungjin. I recommend not searching the songs until you hear them played in the drama. It will be ten times better afterwards. I'll definitely rewatch this again when the time comes. It was certainly a different type of drama I didn't expect would be produced. It wasn't as cliche or oddly different than the rest. In my opinion, this did a better job than Hyde, Jekyll and Me.
