Peridot only wanted to enjoy the company of her online friend. Watching Pearl fluster over her crush, Amethyst teasing her about it, and Garnet observing smugly was fun - yet overwhelming. But when a new girl arrives at her high school, she begins to understand that one person can change someone's life so much.

Lapis is on the verge of failing senior year and needs help in her classes. Even though the relationship between her and Jasper is full of pure hatred she needs to use Peridot's mind to her advantage and maybe even get the little nerd to herself somehow.

Being roommates gives Lapis and Peridot a lot of time to get to know each other and, despite their rocky history, they might just be able to make something entirely new.
