Starless Night「Ziall AU」

Niall's always been the strange kid at school that no one talked to. He never went to parties, never had people to his house.
Much to Louis' dismay, Zayn takes an interest in the first valentine he'd received in all these years that wasn't extravagant, expensive or full of hinting messages. It wasn't a joke to him, and it wasn't a joke to Niall. He's determined to find out who sent it, but Louis knows he can change it to Harry's advantage, even if it won't be to his own.
