Dylan

He's a fairly popular guy, but incredibly disliked. He only goes outside to work, to the store, or on rare occasions. You live with him in a dorm room and interact frequently, but he's never shown you to people or in his streams, although sometimes people in his broadcasts notice some of your things.

He's streaming right now. You were sitting in the hall working on your laptop, and your phone, which was on the bedside table in the room, rang. Dylan, even though he was wearing headphones, heard it, got up, took it from the bedside table, and brought it to you. He went back to his computer, and all his fans were asking whose phone it was and who actually lived with him.
