At first i thought it was only a zombie apolacypse drama but after watching 3 episodes its also saying about our current life the chemistry between actors is very good but i gotta say it cannnot included in a type of violence drama but its acting is incredible but the people in apartment is the best they all play like its thier role i liked this drama very much and i guess it will have a sad ending park hyung sik is gonna die i think but overall its a good drama in the month november to december its ranking is now 41
