My sisters best friend (On Hold)

What if your sister has a best friend and you think he's hot?

This happens to Harry, his twin-sister, Vanessa, has a best friend, named Louis.

For Haz it's love on first sight, but Louis is mostly scared.

Will this turn out to be something amazing or will Harry just end up with a broken heart?

I suck at these kinda descriptions but yeaahhh...
One Direction doesn't exist in this story and I dont own anyone in this story!!
