I saw a short clip of it on Instagram and totally fell in love with the 30-second review, Soohyun's ( Jang Ki Yong) character is so thrilling his skills and ideas are so unexpected. Since I only watched the episodes that have came out so far ep 4 left me on a hoooookkk, Hyunjin ( Nana) is such a good detective and I love how she cares about others but her mother has high expectations like wanting her to be a specific weight or making sure she is home at this time. But this drama is going to be so successful its super interesting .
