This week your husband, Haechan is on leave from work so he decided to take you on a trip to Busan. Of course you are very happy, because usually your husband is very busy, especially since you are 7 months pregnant, you definitely need more attention from your husband

When the two of you were sitting in the train and waiting for the train to leave, suddenly many people ran and screamed in fear. What happened? You don't know, you just tried to ignore it earlier. Until finally, you see a strange creature, it's human but looks very aggressive, they bite everyone and anyone who gets bitten by them will be infected and change to be like them. Is that... a zombie?
