You just use your mouth and eyes and ear cause these thing is the most powerful thing that can kill someone.
How?
I tell ya.
1. Use ear to hear info
2. Make it a thing that can make her hurt
3. Make people believe you. And then done. Eyes on her now. With much hatred and sadness
Thing that can broke her, and in last. Don't hurt her, let other people did and done! She broken now
But.you just remember that you have to put your secret on your brain not anywhere
Cause, she may be broken. But she still can have a revenge, don't trust anyone. Trust your body to keep it.
