You and Cook have been off and on for ages. Your relationship isn’t exactly healthy. However, you often end up hooking up when you’ve got nothing better to do.
You’re best friend, Pandora, is also a close friend of Cook’s by association, and the poor girl was hopelessly in love with him. She didn’t tell you this, of course. She knew your relationship with him was complicated and she knew she never stood a chance with him.
However, after a particularly difficult time. She comes to your house hoping for some comfort. Last she heard, you and Cook had called it quits, for real.
You open the door in a baggy T-shirt that she knew for a fact was Cook’s cause she’d seen him wear it a million times. That wasn’t too strange, you had done that before. She had no reason to believe that he was there. But he was. You had just got done with your usual routine of being tangled in the sheets together.
