Living with other people can be hard. Even if they're your friends, you may not like the way they fold their towels or clean their dishes, and Heaven help you if they decide to bring their dates home. And, this can be even harder if the roommate is someone you don't get along with in the first place, or just generally clash with.
Common plotlines that ensue with this trope involve the roommates fighting for space, one of them being absurdly annoying or otherwise difficult to live with, and a major difference in personalities that cause both of them to be fighting, such as one of them being a slob, and the other a neat-freak. It can occur between enemies, strangers, or even people who are otherwise best friends, discovering their differences while Hilarity Ensues.
They may learn to live together and become close friends, or the bad roommate will need to be escaped from by any means necessary; otherwise, the hilarity and drama will continue indefinitely.

Ao: I'm so happy to be living in the same home, but if this how our first day goes...Misa: It's only natural you'd be worried. You grew up in different environments and now you're living together. I'm sure all kinds of things will come up between you.
