I finally finished the last episode this morning. It might be just me but it was a emotional roller coaster for the last 4 episodes. I was so shocked that Park Ji Sang was back and he came back for Yoo Ri Ta. A bit confused as to why there were more infectees and why they were trying to kill Ri Ta. But my guess is Director may have made an infectee to carry out his plan. But his plan will forever be ambushed. Also, I believe that injection Ji Sang recieved in the end actually made him live without a heart but of course Ri Ta replaced it with her well being. I love this show honestly. I would definitely watch it again but the only thing that will irritate me is Directors poker face. I wanna smash it tbh lol. But I only began watching this show because the actor that played Yoo Ri Ta also played in Boys Over Flowers as Jan Di and that’s a show I’ve watch more than 3 times. But yes a season 2 would definitely fulfill my curiosity.
