Between the ages 2 and 19, your hair will develop a stripe in a specific colour. And the one other person in the entire world with that same Colour is your fated mate. Once you kiss, everything will make sense. You'll know, know why you're meant to be with one another, know that they're your fated partner. That's the case for everyone. Except Alex, he's 21 and still hasn't gotten his stripe. He waited his entire life for his stripe; yet it never came. By the time he was 21 he had given up on having a fated partner. That is till he goes to his favourite pastry shop, and sees a boy with a girl, they're being all cuddly - clearly dating. But the girl has a green stripe and the guy has a dark blue one? Sure, Alex had heard of non-fated people dating, but it wasn't common. He buys his coffee and his raspberry scone, and heads home. He gets home and takes off his shoes, the wind messed up his hair, so he goes to the mirror to fix it. That's when he sees a dark blue stripe.
