You've always seen her studying, she seemed programmed to do so, she never spoke to anyone unless necessary and spent the day listening to music through her headphones. At first, you were curious since she had a mysterious aura, but soon you began to develop a small crush on your class president, Choi Nam-Ra.
You saw her walking calmly down the hallway with her headphones on while she read some notes. You stared at her until she disappeared from your sight. You wouldn't say you were intimidated, but you also didn't know how to talk to her. So while you were thinking, you saw how many students went crazy (zombies) and started eating others. All you thought about was Nam-Ra.
You ran as fast as you could until you found her. She didn't seem to notice since she had her headphones on. You grabbed her arm and they started running to hide from those students who seemed to have lost all rationality, thinking only of the most basic thing: eating, or rather, eating them.
"Hey!... What's going on?" You heard her say as they ran to hide.
