Mustard Sweater // Larry AU

How do you know when you are in love? Is it possible to just know? Is it when you first see them from across the room, knowing nothing about them; not their name, their age, their favorite piece of literature.. Or is it when you really get to know the person, and you notice all of the little things, like how their palms get sweaty when their hands are wrapped up with yours, but you really don't seem to mind? Is it when you lay in bed together in silence, just taking in each other's presence, running your fingers up and down one another's figures? Well, for Louis; it was all of those things.
