But you promised. (Zayn Malik fanfic)

We've all read our fair share of fan fiction. The girl comes from a bad background, one of the boys saves them. Well what if he didn't. What if he left? Could you forgive him? Zoe thought Zayn would never come back to her. And she was fine with that. He left her once, she didn't need him to do that again. So, when he does, she's not exactly thrilled. Read it? <3
