I don't normally watch K-dramas until they're finished because I'm the type who binge watch. This drama though got me hooked and made me wait for weekly uploads. The actors were very good especially Ok Taec Yon, I truly admire him and his charisma is so strong and overpowering. However, when I watched the ending, I kept waiting for a twist that there was a way for Song Woo-hyeol (Ok Taec Yon) to become human despite all odds. He deserves to live and love because he felt the it and he said and showed his true feelings to Joo In-hae. Whoever wrote and decided the ending to be so ugly must be out of his/her mind and a really cruel person. I don't consider it an open-ended ending because Song Woo-hyeol died! It was only in Joo In-hae's imagination and memories that he lives. Of course, as human beings we remember our loved ones who passed away as such, same thing. Overall, the ending is utterly disappointing!
