Review: This is one of my favorite kdrama. It was sooo good. I loved Hyun-Soo because he was so strong. He was half-human and half-monster, so he became super strong. And protected everyone until the end. My favorite part was when he was going to become a monster but the man saved him and comforted him. It was really sad, I cried, but it is still my favorite part.
