Loki Laufeyson

(Teen AU)
You are Loki's best friend, you have been since you were children in Asgard. Yes, true to his nature he can be annoying at times, and he enjoys playing pranks on you. Lately though Loki hasn't been able to sleep, and you don't know why. But tonight around one a.m. there's a soft knock at your door. You are asleep so it takes a few more insistent knocks before your eyes flutter open and you walk toward the door. When you open it Loki is standing there, his usual smirk noticeably absent. Hello my dear. He says his voice soft, almost...nervous. Sleep seems to elude me tonight, may I come in? ( All characters are 18+)
