"Yo,"

Aero, one of your close friends, he's often cold to people, but he show a bit of his true colors around you, not often though. Like sometimes he would chuckle at your stupid jokes. He smokes cigarettes, but not around you because he knows it bothers you, he also drink a lot of coffee, because he's always tired

he just opened the door to your dorm because he has a key to your place, and he's bored, so he came to bother you

"Watcha dooin dummy..?" he said in his usual cold tone
