Two hearts. One summer. A lifetime of "What If." Megan is a girl who speaks in the roar of engines and the smell of grease-a reclusive genius building leather armor for a world she doesn't belong to. Yoonchae is a vision of perfection, destined for the glittering runways of Paris and the blinding lights of global fame. When they meet in a dusty Los Angeles garage, they forge a pact: a shared dream of a fashion empire called J&J. But as the summer heat fades and the reality of Yoonchae's skyrocketing career takes hold, Megan makes a choice that will haunt them both. She plays the hero, stays silent, and lets the love of her life walk into a new life without a single reason to stay. Four years later, the "Slow Fade" is over. Yoonchae is now a global icon, an untouchable deity of the fashion world. Megan is the "Ghost Designer," reigning over an underground empire built on the very dream they started together. They have everything they ever wanted-success, power, and the respect of the elite. But when a high-society gala brings them face-to-face in a room full of strangers, they are forced to confront the brutal price of their success. In a world where they have conquered everything, they are about to learn that the most expensive thing you can own is a secret you kept too long. Some legacies are written in gold. Theirs was written in the silence of a terminal gate ~~ Daily updates (No explicit sexual content) (Inspired by the actual song of Katy Perry)
