5 years since the explosion happened most of the city has been recovered from the apocalypse but people are still not allowed to go anywhere out of the safe zone, Y/n gave birth to Gwi-nam and her son Jeong-Hoon 5 years ago and they lived like a normal family but Jeong-Hoon is a baby zombie meaning he is like his dad Gwi-nam a Half human half zombie. Gwi-nam on the other hand survive the explosion and found a cure with a help of someone now he is trying to find his son and Y/n.
