Getting experience with the guy next door seems like a great idea—until the lines blur. Dev, a geeky first year physics student, has zero sexual experience and he’s determined to change that ASAP. After a bad time in halls of residence, he’s starting the summer term with different housemates and a new plan of action. Ewan lives in the house next door to Dev. He’s young, free and single, and isn’t looking to change that anytime soon. When awkward circumstances throw them together, Ewan offers to help Dev out in the bedroom in return for maths tutoring, and Dev jumps at the chance. They work their way through Dev’s sex-to-do list, but what starts as a perfect no-strings arrangement gets more complicated as their feelings for each other begin to grow. If they’re going to turn their lessons in lovemaking into something more permanent, they need to work out how they feel about each other—before they get to the end of Dev’s list.
