Surviving as the Assassinated Crown Prince

Fiona is an unfortunate princess who has lived her entire life as the crown prince 'Pion' despite being a woman. When a new heir, her younger brother Hubert, is born, she falls out of favor with the emperor and constantly faces the threat of assassination within the imperial palace. With the help of her childhood friend, subject, and genius alchemist Wayne—the second son of a ducal family—she fakes her death, goes into exile far away, and lives a secluded life together. One day, Fiona happens to see Wayne calling out her name and comforting himself... 'Wayne thinks I'm a man. Could it be... does he like men?'
