Stiles hears whispers about the hot grad assistant in his criminal psych class so he grabs a seat near the front and waits for the said GA to come into the classroom.
He isn’t expecting Derek Hale to walk in wearing a soft blue sweater, dark jeans, and GLASSES.
He really isn’t expecting Derek to smile at the class and start passing out the syllabus.
He’s down right shocked when Derek gets to him and stops what he’s doing to stare openly at him.
And Stiles, being the little shit he is gives Derek a cocky smile and a wink as he says, “Long time no see, should I call you professor?”
Derek blinks and looks around the room to see everyone gaping at them. “I’m Derek Hale and this is intro to criminal psychology, Dr. Parker will be in shortly, she was running late.”
The semester ends up consisting mostly of Stiles flirting with Derek and busting his ass in the class to impress him.
Except Derek isn’t taking the bait because he’s trying to be professional. But as soon as he finishes grading the last final for the class he shows up outside of Stiles dorm and kissed the shit of him.
“About time,” Stiles says when they finally break apart, “Want to come in? We’ve got some making up to do.”
Derek just nods and follows Stiles inside the room where they spend the night making out, watching movies, and catching up about the last few years.
