The protagonist, Aria, is a career woman who serves as the captain of the guard for the crown prince of the Rosenberg Empire at a young age. Her lord, Crown Prince Julius, possesses wealth and power, along with looks that no one can deny—but unfortunately, his personality is trash. Aria is exhausted from being jerked around day after day. But surprisingly, Julius might just want to be with Aria...?
A divine-visage crown prince VS a corporate-slave female knight—a precious master-subordinate quarrel couple is born!
