Killian was wide eyed when Koty opened the door, as if he were waiting for his friend's head to start spinning around or for fire to shoot out of his eyes or something. After only a second he reached out to hug him. The gesture felt awkward but that didn't stop him from doing it and after a moment he leaned back and offered his friend a sheepish smile. "Hello Koty." He chimed, reaching up behind him to rub his hands through his hair leaving it sticking up wildly in the back from the fact that he hadn't washed his hair yet that day...or the day before.
