Sterek AU: Stiles gets a job on the Hale farm and when Derek meets him he is so flustered that he kinda accidentally introduces himself as Miguel, their senior farmhand. The workers usually avoid Derek while he’s on the farm anyway due to his grumpy demeanor, so Derek doesn’t think it will be much of a problem.
The trouble is Stiles refuses to leave Derek alone and his incessant chatter is actually sort of… charming. Now Derek is completely head over heels for a man who often asks him if he would feel more comfortable talking in Spanish, and he has no idea how to come clean. Honestly, Derek’s kind of a coward. He would probably go on letting Stiles call him Miguel and insult his family, except you can’t sign a marriage licence with a fake name. He’s checked.
