Na-hye, a Junior-year student at Y High School, was a top student. Smart and outgoing, she was especially adored by her homeroom teacher. Perhaps that was why she was always full of herself. When the teacher wasn’t around, she would act snotty and as if she was better than everyone else in her class. None of her classmates liked her. Everyone avoided her, but Na-hye could not care less. “What does it matter what they say or think about me. They’re all losers”, Na-hye thought to herself. Na-hye was prideful and had a large ego.

Then one cool autumn day, the subject for 5th period was Math, the subject that the homeroom teacher taught. It was right after lunch, and with the cool breeze coming in through the window, most students were nodding off during the lesson. To wake the class up, the irritated teacher called a few students to the board to solve some math problems. Na-hye was one of the students who was called up. One by one, students returned to their seats after solving their problems. Since the problems were easy, no one got them wrong… Except Na-hye. She had read the question wrong and incorrectly solved the problem. This was unheard of considering her skill in Math. In front of the whole class, the teacher rebuked Na-hye saying that it was a stupid mistake. The teacher intended for Na-hye to remember the embarrassment and never make the same mistake again. Na-hye could not lift her head out of shame. Her face turned bright red. The kids could not stop snickering, the fact that the teacher’s pet was being scolded right in front of them was fun and satisfying.

When the teacher left at the end of the lesson, all the kids started talking about what just happened to Na-hye. They sounded excited that they finally had something to hold over her. Na-hye was angry. She blamed the teacher who embarrassed her in front of her class, she hated her classmates who took it as an opportunity to talk behind her back even more, and she was angry at herself for getting the stupid question wrong. Even when she went home after school, she could not get it out of her mind. She hated her eyes for reading the question wrong. “It’s not my fault”, she decided. She rationalized to herself that problem was not her’s, but her eyes. Soon, a terrible sound was heard, and the workbook on her desk was splattered with red.

The next day, Na-hye’s classmates trembled with fear when it was announced that Na-hye had committed suicide by digging her own eyes out with a knife.

After this happened, a rumor spread that whenever a Math problem is left on the chalkboard, Na-hye’s ghost is summoned. It is said that the ghost would stare at the problem on the chalkboard, but her eye sockets would be empty holes.
