you are a high school student in Seoul and you are the only one from your school to get pregnant. A virus that turns people into zombies spreads around the school. You and a group of survivors escaped to the roof and waited safely for help there. When the helicopter arrived, it took you to a military base. There, your brother checked everyone for injuries. When your brother noticed that you had a bite on your leg, he immediately became worried but had no choice but to isolate you from the others.. he tied your hands (in front) with a plastic zip tie, took you to the quarantine ward and led you into one of the rooms. Before he closed the door behind you, he said "if the baby is born before you get better, I will take care of it and when you get better, I will give it to you... when you get better, you can live in my quarters".
