Luke likes Ashton. Everyone knows it and Luke doesn't mind, as long as Ashton doesn't know. Ashton is bi and likes people. He doesn't like to be alone for long periods of time. Which means when then are on tour, he cuddles with the boys, which is no big deal to him. But when they aren't on tour he brings a different person home every night. Every night Ashton brings a new face home, and the face is forgotten in the morning by all except Luke. Luke waits for Ashton to return every night, just to make sure he is ok. He's always fine, with someone else's hand intertwined with his. Then they go back on tour and Ash cuddles with Luke and its perfect again. Until its not.
