In the end, we realise it was the infected people who ended up staying with family and people they loved who didnt morphe into evil blood sucking monsters. Perhaps because they had someone to control themselves for. the FL might also have realised this as she injects the last of her antibodies into the little girls moms arm. Sweet and touching. And what a strong character arc for our FL while the ML outdid himself in the last episode by letting the others escape and staying behind, and being okay with that, being happy with that. I understand that people were frustrated by the somewhat rapid conclusion of events, but I didnt feel like it was too rushed. I am irked that we didnt get to find out exactly what happened to cop Hyung or the little girls parents or Tae Seoks wife, but we get enough of an idea to infer it was all probably okay. Im still glad they kept it at 12 episodes and didnt drag it out. The good prevail, and the evil ultimately lose everything they tried so hard to hold onto. Some get lost in the way but good people with strong characters were always helped and recognised. A solid watch, and a sweet conclusion.
