One Night Soulmate

When you meet your soulmate your hair goes from grey to the colour of their eyes. Somewhere on your body your soulmates initials will show.

Louis wakes up with a hangover after a one night stand and can't remember the night before. All he knows is Niall dragged him to a university party. The boy he wakes up next to has his head buried under the pillow so he can't even see who it is.

He gets dressed quickly and has to sneak out of a house he doesn't recognise. When he gets home he swears and punches the wall. His hair is green and on his hip are the letters HS.

He knew he shouldn't have gone to that party.
