Forgotten Title Girl who can delay her death

the main character runs over a girl due to reckless driving. Once he does so, she appears telling him that he killed her. She then begins to go on a killing spree for the remaining week or two she has left and the main character assists her.

I already finished this, but I have fond memories of it and it frustrates me forgetting what the name is.

 

What the fuck is wrong with her? If I were her, I would kill the guy who ran over me instead of some innocent people.

 

Pain, Pain, Go Away

 

Soooo.... does her murdering others delay her death?

 

Thanks Xaist, I remembered the title being something that only made sense midway.

 

She delayed her death a week, she promised to kill the Protagonist last after she was done with all her grudges. The people she killed were all bullies or her abusive dad.

 

Nope, she just some past grudges that she wanted to get revenge on before she dies.
