Holding On (A Harry Styles Love Story)

I've never understood love. I don't understand how you can have such strong feelings for one person. I don't understand how, even when they've hurt you so badly, if they're in jeopardy you can forget about anything they ever did to you. I don't understand how they can play such a huge role in your life.
When I was 17, a boy changed my life forever.
His name is Harry Styles.
