This Drama was such a masterpiece !! I honestly didn't think I was gonna love this drama as much as I did but I was wrong. I would say if you're not really into thriller shows or if you want to get into them, I would recommend this drama for you. As a person who is not that much into thriller shows and just started this is a good choice.

The OST is now considered one of my favorite OST. I thought that the OST worked really well with the story

The acting was my favorite throughout this whole show. This cast was amazing and really outdid themselves.
Lee Jung ki was the best throughout this whole show and played Hyun Soo very well and showing us different sides of Hyun Soo.
Moon Chae Won who played Ji Won was also amazing and I really enjoyed her acting she plays Ji Won amazing in making this character come alive and portrays all of Ji Won complicated emotion and made the feel real and raw.

For the romance, I loved it, Ji Won and Hyun Soo had such an emotional journey which makes them feel real, and you can't help but want them to have their happy ending. Also, Lee Jun Ki and Moon Chae Won are great together and their chemistry was solid that I fully believed that Ji Won and Hyun Soo were a married couple.
