Rosa is known as the beautiful and charitable countess daughter, admired by many. But in truth, she’s a devoted “腐女子” (fujoshi) — someone who passionately enjoys male-male romances. One day, at age 14, she meets her half-brother Bernardo, a “once-in-a-thousand-years” ideal “uke” (male receiver role). Rosa swiftly drafts a plan: “Bern-tan, total uke plan!” However, her flamboyant behaviour is repeatedly misunderstood as noble and sincere by others… and soon her fantasies begin to affect princes, princesses, and even foreign royalty!
