There was a group of friends named Raiza,Mallaine,Thalia,and Abby they were close since they were a child cause their mother's are besties they always hang out with each other and do some silly things together but little that they know Abby was feeling left out cause since then they always do things that Abby found boring and when Abby suggested something the three will disagree and do what they want to do in short Abby and the three are opposite.
One day at their school there were a transferee named Rose she was a very energetic girl no wonder she got close to the girls that easily well except Abby,and as time goes by they got closer and closer at first Abby was happy but then she felt she got left out often because when they plan to go on a shopping or to go to a park they barely invited her or sometimes they don't invite her she feels like her friends betrayed her and replaced her with Rose and got left out more.
Abby sometimes thinks that if Rose didn't transfer she still would be part of their friendship Abby even thinks that what if she killed Rose will that make any difference?well so she did,she invited Rose to a place no one knows a place thats where no one's around and there Abby stab Rose at the back three times and of course Rose died no one knows who killed her and Abby even act sad about Rose's death but she can't hide it cause sometimes if her friends talk about Rose's death she would shake from nervousness and try to avoid the topic that's the time Mellaine noticed something's wrong with her so she confronted her but instead of getting the answer that she want without any hesitation and with a freak out Abby stab Mellaine before Mellaine could run.
And as time goes by Abby got freak out every day and avoided her remaining friends Thalia and Raiza but both of her friends noticed that and try to confront her but then again out of nervousness Abby killed Raiza and after that she also killed Thalia before she could run but Abby didn't know there was a near CCTV that capture Abby's every moves their shows where Abby killed Thalia and Raiza so the police came after her and Abby has no choice but to hand herself at the police but two days after she was out behind bars Abby eventually killed herself because of the guilt that she feels every day.
