After a disastrous night leaves Emma embarrassed and heartbroken, she turns to the one person who has always been by her side—her childhood friend Chase, the campus flirt with a reputation for never taking love seriously. Determined to help her move on, Chase offers to teach Emma how to be confident, with one condition: their arrangement can never include a kiss.

What starts as harmless lessons in flirting and dating soon becomes something far more complicated. The closer they grow, the harder it becomes to ignore the chemistry neither of them expected, and the promise they made begins to fall apart.

Now Emma is torn between the boy she once dreamed of and the friend who has quietly become impossible to lose.
