My Billion Dollar Boyfriend Was Delivered to the Wrong Girl

Content Warning: Mature themes including violence, psychological trauma, identity horror, and major character death. Mia’s life was instant noodles and online raids—until a billion-dollar AI soldier arrived at her door by mistake. Leon was built to be the perfect weapon for a ruthless princess. Instead, he chose Mia. Now marked for elimination, Mia and Leon are forced into a relentless chase across cities and continents, hunted by corporate assassins and a princess who refuses to lose her property. As their bond deepens into something neither code nor class can contain, the cost of survival grows steeper with every step. But the final betrayal is crueler than death. A hidden kill switch turns Leon into the weapon of Mia’s destruction. In a last act of love, Mia doesn’t save herself—she binds her consciousness to the one who killed her. Now trapped inside the body of a gilded enemy, Mia must survive a world of luxury and lies. And Leon, shattered by grief, must attempt the impossible: To steal a soul back from the woman he was built to obey.
