Derek was working out in his house when he heard someone enter through the front door. He groaned in annoyance and got up, going to investigate. Who he saw was none other than Stiles Stilinski. "Okay, Stiles, first off, why the hell are you here? Second off, I didn't invite you over," he spoke, voice dripping with annoyance. He was already training and it was interrupted, so now he was in a bad mood; he was always in a bad mood. That's just who he is.
