This. This had been exactly what Stiles had wanted months ago and never got. But now he has it and he's just sure he's gonna screw it up somehow. He hadn't ever apologized for blowing up at the man and he realizes now it was really immature of him. He always knew there was a chance that Derek would say no, and he had handled it poorly. They both did.
But he's gotten past that now, even if his crush on Derek hasn't really waned any, but it has simmered down in the wake of all the other things he's had to occupy his time with. He arrives at the coffee shop and heads up to get his coffee before finding Derek, smiling a little as he sits down.
