Making a book but don't know what title I should give it. Please help

Okay so I want to make a book about grooming (I'm thinking of making it in a few years from now). A 24 y/o guy is grooming a high school girl. It works and such. I'm gonna say this it's a tragedy. There won't be happiness between the older guy and the high school girl. I'm gonna make the girl die by the 24 y/o guy. But I have a problem. The problem is that I don't know what the title should be. Please help. I want something with a #. Like #Don'tTextStrangers or #StopGrooming. Those are just examples. I suck at coming up with titles. So please help.
