Intro
My sibling was kind. They were so kind it was a problem.
The type who would do any favor and couldn't say no. Was that the cause?
My sibling is dead. They died because they were bullied by those kids just because they stopped helping after doing everything for them until now.
I willingly decided to kill. I felt empty somewhere when I gripped the knife. There were no regrets when I carried out the plan for the first time. Guilt? They killed my sibling first. My only guilt is the guilt of not being able to protect them.
The detectives must be gathering evidence to find me. Police? What use is that. Who compensates for my sibling's death? Who compensates for my sorrow? I have to take revenge myself. Run away? I have no intention to. I must tell you all as well. This cruel truth. This side of a filthy world.
