The Protein Noblewoman’s Broken Engagement: ‘It’s Too Late to Grovel After My Muscular Domestic Reforms Make Us a Great

Alicia, a ten-year-old princess of the small and struggling Kingdom of Luminaria, secretly carries memories from her past life as a male health science student and aspiring bodybuilder in Los Angeles. Driven by her favorite maxim—“Muscles never betray you”—Alicia uses her modern knowledge of fitness, nutrition, and sports medicine to enact bold reforms and strengthen her impoverished realm.

Initially spurned by an arrogant prince who seeks a more powerful alliance, Alicia vows to prove him wrong. She improves the miners’ working conditions by supplying them with essential minerals and protein-rich foods, introduces new farming techniques, and raises chickens to secure a steady supply of eggs. Under her leadership, Luminaria’s economy and military prowess rapidly flourish, culminating in a dramatic shift in power dynamics among neighboring kingdoms.

When the very prince who broke their engagement returns, humbled by Luminaria’s newfound might, Alicia has already built a thriving nation—one poised to unify its region and usher in an age of prosperity that will be remembered for a hundred years.
