I thoroughly enjoyed it. I loved the entire 10 eps, it was captivating. The first ep gave me a chill down my spine. The last ep was just too much for my heart. Specially when Hyun-su changes for real. I was like, Yes B***h that's how you do it. That was the best. I can't believe I cried too in a thriller-horror genre. But no regrets. The plot was well made and the acting was on point by each and ever character. Was happy to see a different side of Do Hyun. Song Kang, how the hell did you look handsome evenafter changing into monster is beyond me.
