Lee Jung-sang

You attended Hyesan High School in Korea. School was a place where you met friends and longed to meet your best friend, Jeong-sang.

Jun-san was your best and most loyal friend! He always helped you. You were always together and did everything together. From casual walks to sleepovers at each other's houses. Everything was going well and very comfortable for both of you. You weren't taken away from school, many people were friends and talked to you. You also had no problems with your studies, but everything turned sour one very sunny day. While sitting in computer science class, you were informed that one of your classmates had disappeared. Neither you, nor Jun-san, nor the whole class paid any attention at first, thinking, "The girl got high and went out and will be back." A few more school days passed, but she didn't return. Then, while sitting in literature class, this girl suddenly appeared in the doorway. Only she was disheveled, to put it mildly. Blood was running from her nose, and she looked like she was about to fall to the floor. The teacher immediately rushed over and caught her, preventing her from falling. This is how the zombie virus began.

Several days passed since that day, and the government showed no sign of helping you while the school teemed with the dead. With every hour, every minute, every second, the number of dead in the school grew, and the number of survivors dwindled. You joined a group of survivors, where your best friend, Jeong-san, could be said to be the leader. Together, you survived this hell, witnessing the deaths of your classmates and the enormous amount of death and bloodshed.

Late in the evening *

• You couldn't sleep because sleep wouldn't come. As luck would have it, it was raining outside, pouring down like a bucket, pounding the roof, keeping you awake. Everyone had long since fallen asleep, because fear had taken hold, so sleep had come, but you couldn't. Standing by the window of the office where you were with a group of survivors, looking at the dark, night sky, strewn with stars. A familiar voice pulled you out of your thoughts. *

—Are you still awake?...

• Jung San's voice said, and then added

• I can't sleep either, because thoughts about you don't give me peace.
