“Hello? Who is this?” I asked because someone suddenly called my phone number while I was inside a private restaurant where my boyfriend and I are currently having dinner, and tonight we are also celebrating our fifth anniversary. While I was waiting for the person who called me to speak, Mike suddenly stood up and knelt in front of me. I was shocked because I thought he was planning to propose to me, but I was surprised when the person I was talking to spoke on the phone.

“Are you Sulin Lim's family? She was found lifeless inside her classroom and…” I didn't hear the rest of what he said because I dropped my phone when I heard what he said.

“I'm sorry, but we have to separate. I love someone else, and I want to be with her for the rest of my life.” Mike said to me, so I felt double pain in those moments. My eyes continued to tear up until I didn't realize that Mike had already left and that I had been sitting there alone for a while, stunned into nothingness.

“Ma'am, excuse me, but our restaurant is about to close.” Only then did I come to my senses when the waiter there approached me and informed me that they were about to close. Only then did I realize the time and only then did I notice that I was the only customer left, so I stood up and left the restaurant. I heard my phone ringing again, calling me repeatedly from the hospital where my sister, Sulin was. I don't believe what they told me, and how could she die if she was almost fine the last time I saw her this morning before she entered their university?

So, I just went straight home instead of going to the hospital. I found that she was not there, and it was eleven o'clock at night, but she still did not come home. I was just sitting on the sofa in the living room waiting for her to come. But the next morning came, and I didn't realize that I fell asleep on the sofa waiting for her. I immediately stood up and went to her room, but she was not there nor did I even see her things there. I tried to call her phone number and in less than ten seconds she immediately answered it.

“Hello, Sulin? Where have you been and why are you still not coming home?” I said angrily to her when she answered the call, but I heard a response from an unfamiliar male voice.

“I'm sorry miss but may I know what is your relationship to Ms. Sulin Lim?” he was curious, so I didn't respond to him immediately and curious.

“I'm her sister. Who are you? Why are you holding her cell phone?” after I said that, I suddenly dropped my cellphone and ran towards the hospital wearing only one slipper on my feet and nothing with me except my wallet.

“I am sorry to inform you that we found your sister lifeless inside their classroom, and it was too late when we took her to the hospital.” The police officer I spoke earlier told me about Sulin.

When I entered the hospital, I noticed that some nurses, doctors, and police officers were staring at me there. I slowly stepped my feet towards where they were while I was panting.

“Are you Sulin Lim's sister?” When he said that, I immediately realize his familiar voice because he was the policeman I talked to earlier. I nodded my head and swallowed deeply because of the intense nervousness I was feeling. Then he opened the door to the morgue and I slowly went inside. I noticed that there was no one else in the room except for a dead body covered with a white cloth. My whole body was shaking as I approached her, at the same time tears were falling from my eyes. I stopped in front of her and looked at her from head to toe. I slowly lowered the cloth covering her face, and I hoped that Sulin was not that person. But I covered my mouth when I saw her two eyebrows where her right eyebrow has a scar, a sign that she fell down the stairs when she was only ten years old. So, when I saw the scar on her eyebrow, I knew it was Sulin.

My knees fell from the shock, while whining loudly from the pain I felt in my chest.

“Sulin!” I kept shouting her name and tightly holding her hand with wounds and bruises. Because of that, I stood up and removed the cloth covering her where I discovered that she not only had such deep wounds and bruises on her hand but on different parts of her body. But all of this, she hid from me and did not say anything. I have no idea what is happening to her, and she has so many wounds on her body. I asked the police what happened to her and where she got her wounds, but they didn't answer me as if they were protecting someone. Furthermore, I tried to file a case against them, but that was useless because even the prosecutors, lawyers, and judges were covering up the person who did this to her. So, I promised myself that I would make them pay for what they did to my sister. All accomplices in the crime, who murder her, will suffer in hell.

“I sympathize with Sulin's loss.” A young student wearing a uniform like Sulin's said to me that I thought maybe they were in the same class, or they knew each other. She just looked down, but I noticed that she was smiling, so I looked down at my foot where she was staring at, but there was nothing to laugh at, so why was she smiling as if she were laughing at someone?

I was about to speak, but she turned and left with four female and male students. When they left the door, she briefly turned to Sulin's coffin with a mysterious smile on her lips. With the sudden change in her facial expression, I thought that they might have something to do with the wounds and bruises that Sulin suffered all over her body, so I immediately ran to chase them, but they immediately got into their cars and left. I will never forget the smile on her lips as if she were behind everything why my sister died, and I feel that she is that person, the one they are trying to protect. In my anger, I clenched my fists tightly as I stared at them intently.

After Sulin was buried, I immediately went home to rest in her room. Inside her room I saw and discovered some things. I read in her diary every torture that was done to her and who bullied her at the university she attended. On the last page she wrote, I read that someone dared to help her.

“Rhey, how are you doing? Are you still feeling bad?”

Rhey is the person she refers to in her diary who saved her, that's why I will do everything to repay him for helping my sister, Sulin.

I applied to the university that Sulin attended as a Chemist Professor. Before I came here, I used to work in a big laboratory as a scientist. So, when they saw my profile, they immediately hired me as a professor at their university. I also changed myself so that I will not be recognized by anyone who knows the former me, the former Monica Lim. Using the savings I had for Sulin's future, I just bought a condominium near the university and I also bought a car as well as luxury items that I didn't often buy before. I dressed like a model, so I immediately got the attention of the students studying there. I want them to come to me and get their attention.

“I like your kissable lips.” I heard a man say when I went to the yard to smoke, but I realized there were several groups of students there, and I also saw Rhey there where they seemed to be bullying him and insulting him. So even before the man kissed him, I took out my cell phone and put on my hat and covered my mouth with a mask, so they wouldn't recognize me. I also changed my clothes, so they wouldn't notice who I was. I frequently carry extra clothes because I have to disguise myself while I'm inside the university. Then I took a picture of them to grab their attention, and then I sped away where they immediately chased me. But I managed to escape from them and I just threw the clothes I used in the trash drum because they might suspect me. I put on my professor uniform again and turned back to Rhey where I found him just sitting there stunned and shaking with fear.

I accompanied him to his house, and after that day I never saw him again. He hasn't come to my class for more than two days, so I'm worried about him. I thought of visiting him at his house to make sure he was okay, and I noticed that his face was still pale from shock. But after a week I saw him again in my class, and he was doing well again, and he was able to smile again.

As I was walking towards the restroom, I noticed Monique's group inside while they were bullying a student. Her face was wet as well as the uniform she was wearing as if they forced her into the toilet. I saw Monique calmly applying lipstick in front of the mirror as if nothing were happening there. They let go of the student immediately when they saw me and ran out of leaving only Monique who still hadn't finished fixing herself. I stood next to her to wash my hands, but I was stunned when I heard what she told me.

“You look so familiar to me, but I can't remember where we met. How about you? Don't you remember me?” She said as she faced me with one eyebrow raised.

“I don't know what you're talking about, but I think I've seen you before.” I replied to her at the same time she grinned, and she handed me a paper with an address written on it.

“Can you pick up my cat, Mellow? I have another class and I have plenty of projects to take care of later, so I might not be able to take him to the pet clinic. Is that okay with you, Ms. Monica?” when she said that I clenched my fist, but I forced myself to smile at her because I didn't want her to notice the emotion I was feeling right now. I just nodded my head and took the paper she was handing to me, then she turned and left the restroom.

I went to the address written on the paper. Furthermore, I took her Persian pet. I didn't give it to her right away, instead I went to my laboratory and injected her with the virus that I had invented for a long time. With that virus, I will surely bring justice to Sulin's death and make sure that none of them will survive.
