You Promised

'Friends with Benefits' I'm sure you've heard all about it, books were made on the topic, movies, songs, you name it; it's been done. Everyone knows, you can't be friends and have sex, it never works out. One ends up falling blatantly head over heels for the other and ruins the whole arrangement.

So what happens when Karina Carpio and Zayn Malik get themselves into the same situation?

Will they keep it in control, or will reality slap them hard in the face?

"Promise, you want fall for me?" she said, "I promise."

Is this promise enough to keep them going? Will it keep them together on the terms they agreed to, or will it all fall apart?
