Louis has a lot of friends but he's by far the closest to Harry. The two boys been best friends since primary school and have remained very close since.
When Zayn randomly blurts out that he thinks that Louis and Harry like each other the two of them just dismiss Zayns "theory" but it makes Louis start to think.
Does he like Harry more than just as a friend?
Louis decides that they would never like each other as more than friends but when Harry shares a secret with Louis the two of them begin to become even closer than before.
Who knows, maybe they'll end up together after all?
