My name is Sun. I'm a normal 20-year-old boy. My appearance isn't that handsome. My personality is quiet. I like to talk alone. Because in real life I have few friends. And not that close So I created an imaginary friend. I know that my monologue sounds funny to others. Some people may even consider it a ghost. But sometimes I can't help but do that.

When I was in elementary school, I didn't have any close friends. It's probably better to have had close friends. That friend was a quiet person like me. We had been close for about three months. But when he plays with me He was often teased by his friends about how he could hang out with such strange people. After being teased for a long time, he distanced himself from me.

I could only play with toys alone. Read a book in a quiet corner of the library

My nightmare began when I was studying English with a teacher in Grade 4. The teacher was in her 30s and was the hottest female teacher I had ever met. Teachers often scold children for minor things, such as doing homework incorrectly and not being able to answer questions in class. The teacher's scolding is more of a form of scolding for satisfaction than a scolding for the child to improve.

I tried to understand the things the teacher taught to the best of my ability. But what can I do? I was not originally good at English. The teacher once called me to answer a question in class. I answered incorrectly, so the teacher harshly scolded me for being stupid. Not paying attention to study Will this type of intelligence be able to get into good Mathayom 1 exams?

That incident caused me great embarrassment. I spent my life feeling belittled about my abilities. I just think that tomorrow I have to study with this teacher. I was so stressed I almost vomited. I pretended to be sick many times so I wouldn't have to go to school. But the plan was unsuccessful. My mother caught me and scolded me for being a lazy child.

I was a child with less wealth than the rest of my class. I had to spend money sparingly. I hardly have the opportunity to buy trendy toys like other friends. My school supplies are mediocre. Everything that makes up who I am is ordinary. Ordinary appearance, even somewhat ugly. Academic results are in the middle range.

It's called nothing that stands out in particular. Originally, I was used to the way things were. Just think that your body is strong. How good is it to have the opportunity to study? But the teacher once said in the middle of the class that he felt sorry for my family. They were poor. The parents intended to send them to school but ended up having stupid children. The teacher's words continued to echo in my head for many years to come. I feel guilty towards my parents for not being very smart.

I once had a teacher shout and scold me while teaching for not paying attention to my studies. Even though I just sat and studied quietly like other kids. So I shouted in response, "So the teacher thinks that he has intended to teach?" Scolding a child so loudly Do you think I want to study with the teacher?" The teacher heard this and was displeased.

Hit me hard on the head. along with calling the parents to meet and having their behavior points deducted according to regulations That made me very upset. I admit that it was my fault for speaking with emotion. But the teacher's actions weren't wrong at all?

Life continued until the end of primary school without much happiness. When I was in high school Meet a wider society and accept differences. I have close friends who understand me. I have met teachers who do not interfere in students' personal matters. It was there that I was able to be myself again and gradually forget the pain that was in my heart when I was in elementary school.

After graduating from high school, I continued my studies in the Faculty of Engineering at a university. Have lived a normal, happy life ever since. But then something unexpected happened. One evening, on the night of the full moon I realized that I had forgotten something under the school building. It's a keychain that a close friend from high school made for me. Because my dormitory is not too far from the school building.

So I decided to go get it. The atmosphere in the school building at night and during the day was completely different. I felt the cold sensation of an unidentified visitor. Looking at the big tree at night gives a very desolate and hair-raising view.

I looked all over the building for the keychain but still couldn't find it. At that moment, I gave up. I think someone might have taken it. Or the housekeeper picked it up and threw it away. But then a sound came from the stairs. "Finding a keychain? Follow me." I was very confused. Because I was sure that no one but me was in that area. But curiosity won out. So I decided to follow the mysterious voice.

“Who are you?” I shouted in a mysterious voice. I am now sure that the owner of the mysterious voice is definitely not human.

“I am the ghost of a former student of this university. I committed suicide for reasons related to past abuse. I have the magical power to grant one wish. is to go back in time and take revenge Do you have anyone in particular you want revenge on?” a mysterious voice asked me.

“Uh, now I don't hold a grudge against anyone in particular. My life is happy. And..I have another doubt. That if I take revenge and cause his death Am I going to be prosecuted?” I replied with doubt.

“Be careful, young man. Don't worry. You won't be prosecuted. Revenge will be another form of the young father taking action against the revenger. It looks like a body without a soul. But the young man isn't dead yet. Our spirit can be removed."

“Then can I take revenge on my elementary school teacher? But it doesn't have to be too heavy." "How do I get revenge?" "I want it to be a way to make the teacher hallucinate."

"This is interesting. Now, let me give you this blessing." After saying that, a bright light appeared in front of him. It is a hint that the owner of the mysterious voice has already accepted the wish.

Cut to that teacher. It was now time for the teacher to go to bed. Suddenly, in the dream, a picture appeared of the teacher who had scolded the child with harsh words in the past. Along with the voice echoing in my head "You're an inept teacher. Cursing children with vulgar words." "I hate teachers. Go die." "I've always hated teachers. I want teachers to be yelled at loudly. Teachers who are rude like this are really a mess in the world."

The teacher woke up from a nightmare at 4:00 a.m. I thought it was just a dream. But a hallucinatory image appeared in front of him. It was a picture of many humans with scary faces. distorted face They were rushing in to hurt themselves. However, All you see is an illusion. So the teacher took medicine that had the effect of making him sleepy in order to fall asleep.

The next morning, the teacher went to school with a pale face from lack of rest. When making eye contact with other teachers and students The teacher saw them gossiping happily. So he quickly walked away. But the teacher saw them running after them. Looks like it's intended to do harm. So he quickly ran to the rooftop.

But they continued to follow. Suddenly, one student pulled out a gun and threatened to shoot. with utmost shock The teacher ran away and fell from the rooftop. The body quickly fell to the ground. It appeared as a lifeless body lying in a pool of blood. Much to the shock of people in that area. No one is at fault in this matter.

Because the picture the teacher sees is an illusion. In the eyes of outsiders, they could only see this teacher acting strangely, suddenly running towards the rooftop and jumping down.
