Love Struck- a Harry Styles fan fiction

Madelyn and Harold. The best friends of high school. Madelyn rejected Harold's proposal, he grew up to be a HotShot, amazing singer and everybody's best friend. But, not a person in the world except of him and Madelyn knew about his broken heart. Madelyn was a nerd in high school, probably anorexic. Harold, was cute and chubby. Nobody would've thought that a guy like Harold would propose Madelyn, that's why it says 'expect the unexpected'. After 8 years when they meet, will they recognise each other, the good girl had turned into a popular, pretty and perfect image while the good boy became a singer. Did the fame, money and popularity make them snobbish or they just continued to be friends, or maybe more than that?
