Born into the renowned martial Rittermeier family, Leona is a powerful knightly noblewoman who scoffs at traditional gender roles. Forced into an arranged marriage party by her mother, her sexist fiancé insults her and demands she be a passive, submissive trophy wife. Unable to stomach it, Leona flees to the courtyard, where she encounters Second Prince Friedrich. Known mockingly at court as the “weak prince who can’t even hold a sword,” Friedrich calmly confronts and drives away her arrogant fiancé. Treated with genuine respect for the first time, Leona discovers a deep, lonely sincerity behind Friedrich’s frail facade. Thus begins a destiny-bound master-servant romance between the kingdom’s “strongest” lady knight and its “weakest” prince!
