Adopted by Larry

Savannah is a thirteen year old girl, who was abandoned at the age of five from her parents passing in a massive train crash. She's lived in London's Orphanage for Abandoned Children ever since, parents not wanting, mostly not even bothering to look at her anymore now because of her age. Savannah used to be a mella dramatic, loud, crazy girl. Then at the age of about nine or ten, she fully realized what happened and grew up a little. She's now a sarcastic, tad more mature, girl. Parents still wouldn't look at her because she was almost a teenager, and all the parents ever wanted were adorable little infants and toddlers. But what happens when her luck turns and someone finally adopts her, but it turns out to be two members of the biggest boy band, Louis Tomlinson and Harry Styles, when as far as people know, they're both as straight as a line. I mean, Louis DOES have a girlfriend, right?
