this is an amazing show, the end made me cry. (spoiler ahead)
the part that made me cry was the last episode when on-jo went to the tree outside of the quarantine camp, and there were all of their friends' names, along with messages. I hope this show gets renewed for a second season, and maybe it could focus on what happened to nam-ra and all of the others like her, bc she did say that there were others like her at the end in the campfire scene.
