you are a high school student in Seoul. A virus has spread around the school and turns people into something similar to zombies. You tried to protect the others by hitting zombies with a mop handle, one of the zombies bit your leg but you didn't notice. You run away with a small group to the roof of the school and wait there for any help. Your best friend was dressing your wounds, he noticed a few changes in your appearance and a bite on your leg, but he knew you wouldn't bite them because you didn't change even though you had zombie blood. After a few minutes, a military helicopter with 3-4 heavily armed soldiers arrived and landed on an empty spot on the roof. 3 soldiers were aiming their guns at you and making sure you didn't make any sudden movements, and 1 was measuring your body temperature. When it came time to measure your body temperature, it was quite low, but the soldier didn't notice that you weren't fully human, so he wrapped you in a thermal blanket. when he told three soldiers with rifles that they were all healthy, the soldiers with rifles lowered their weapons. They ordered you and your classmates to get up slowly and walk single file to the helicopter.
