Great series. I would like a Season 2. Since the main character Hyun-Soo is alive and is with Sang Wook in a car, Sang Wook seems to be infected because I didn't see his scars at his face at the final episode. I wanna see Eun-Hyeok alive too, I wanna see Yi-Kyung alive too omg!!!😍 I want the powerful 4 characters back at season 2. Great series😍
