'I rolled off my bed drying the last tears. The ones I swore I'd never let escape my eyes. Not for that. Not for him.' Hannah lives in Mullingar, Ireland. Her life is pretty simple. Nothing much to it, really. Except she has to be cautious whenever she turns on the radio, the TV or when she reads a magazine. Why? Because she doesn't want to see his face. The boy who ruined her. A year passed since she managed to escape him. She's been trying her best to forget everything. Unfortunately for her, his year-old explosive fame doesn't play in her favor. Obviously. Having dated him for 3 years before he became famous, she can easily laugh at the image he and his boyband claim. Respect towards women? Please, she thought. Persuaded that with his new fame he's forgotten about her, which, in her opinion, is better anyways and wished she could say the same about her, she'll quickly be proven wrong. Knowing him by heart, she could reckon that when Niall Horan wants something, he gets it. And that's exactly what he did.

She doesn't remember anything. Their first date, their first kiss, the first time he bought her flowers, their first fight. She doesn't even know who he is. She's forgotten something horrible, something no one wants to remind her of. So what exactly happens when everything disappears?

When Sam's boyfriend of 5 years cheats on her, will she go back to the love of her life Niall Horan, or find someone new?
