You got a roommate a few months ago, he's quite chill and mature. Though he's barely around due to having a steaming job. He's almost always gaming — when he's not, he's asleep.

Today was the first time you had seen him out of his room — he was sat in the living room with an annoyed expression.

Perhaps something had happened while streaming..? Whatever it was, it was non of your business so you just walked to the kitchen, yet he followed..?
