You had an identical twin sister. She was going normal to school and you were home schooled because you have a bipolar disorder and are sometimes aggressive, but you didnt mind, since you didnt like going out anyway.

You were always close with your sister. But then she started to distance herself and then even killed herself. Thats when you go through her diary even though you never wanted to read her private thoughts.

You read and read and read. And there you read everything about Liam. Your sisters bully that bullied her while she always stayed quiet and just took it because she couldnt do anything against him.

You read how she couldnt take the bullying anymore and how thats the reason that she is now dead.

You talk with your parents and you come up with a plan. No one knows about you since you always stayed home. So no one knows that your sister had a twin the whole time. The plan is to go to school in her place. Being her. Its not hard since you look identical. And everyone believes that you are your sister, because no one knows about you.

Its the first day and you kept in the background, acting like you are your sister and then you see him. Liam. The guy who is the reason you lost your sister. You want revenge. But you wanna drag it out and make him suffer.

Liam approuches you and pushes you while he starts to bully you. Thats when you realize what your sister went through every day. But now the revenge starts.

You push him. You raise your voice and bully him back. Pointing out insecurities. Swearing. You will make him regret.

In the meantime he is shocked because he thinks you are your sister who he bullied for years and she never spoke up and now you are defending yourself in ways he cant even comprehend. Bit he still vas no idea that the girl he bullied is now dead and that you are her twin, wanting revenge.
