Let Me Just Double Check [Lashton AU]

"No, it needs to be perfect."

"I have to wash my hands again, one more time."

"Let me just double check."

These are things Ashton says on a daily basis, having an extreme cause of OCD. And when he is roomed with Luke Hemmings in university, who's a gay slob that's overly energetic, he thinks life is trying to ruin everything for him. Especially when Luke has a need to always annoy him and cling to the boy, even though he's straight.
