I took my own life because I could no longer endure years of bullying at school. But after I died, I couldn't be reincarnated and could only wander the world.
In the end, they got into good universities. Years later, their parents stood in the way of their son's future, so they killed them.
When I opened my eyes again, I had been reborn as a frail young lady.
I wouldn't stop until I had repaid them, one by one, for everything they had done to me and my parents.
