Some fires start with a spark. Others burn you alive.

Y/N Kato never meant to fall for Katsuki Bakugou. Especially not with his explosive temper, complicated reputation, and toxic girlfriend, Izumi, hanging off his arm. But one impulsive game of kiss the bottle at Kirishima's party changes everything. One kiss-meant to be meaningless-leaves a mark neither of them can ignore.

In the fallout, Bakugou does the unthinkable: he breaks things off with Izumi. Everyone thinks it's over. But for Y/N, it's just the beginning.

Behind closed doors, she and Bakugou start something raw, passionate, and completely secret. For two and a half weeks, it's fire-uncontrollable, consuming, and dangerously addicting. He touches her like he means it. Looks at her like she's the only person who sees him clearly. And for a while, she believes it's real.

Until he betrays her.

The Only Exception is a slow-burn, emotionally explosive romance packed with secrets, betrayal, and heartbreak. Because sometimes the person you think is your exception... turns out to be the worst kind of rule.
