Grayson has only five rules for himself. 1. Stay away from his toxic ex, Y/N. 2. Don’t unblock her number. 3. If you’re both in the same room, don’t look at her and keep the conversations to a minimum. 4. He absolutely cannot under no circumstances have any sexual relations with her because he will get hooked back onto her like the drug that she is. And 5. He cannot forgive Y/N. His rules were solid. He’s kept to them for a year and a half.. until he see’s you at a party.. looking more dangerous than ever.
