Kevin and Elle have been best friends since their freshman year of high school. They have been platonic for so long that they are almost like siblings. Now it's their freshman year of college, and they attend the same university. Kevin and Elle's roommates, Veronica and Felix are a couple. The roommates are shocked that their new friends are not a couple. Veronica takes it as a challenge to get "KEllevin" together. To do so, she initiates a bet: Kevin and Elle must live together for the thirty days of September. If they remain platonic, they win. If feelings are developed, Veronica and Felix win. The winning couple gets the boys' dorm room, which is much larger and more updated. It even has two bathrooms. Will Kevin and Elle manage to keep their sibling-like bond, or will Felix and Veronica change everything with their bet.
