Therese is the daughter of an impoverished marquis, and her family’s empty coffers leave her constantly worrying about money. When she learns that simply becoming a candidate for the prince’s consort comes with a lavish sign-up bonus and the possibility of a high-paying position as a lady-in-waiting, she immediately throws her hat into the ring. She has no interest in romance or royal ambition; all she wants is financial security and a steady paycheck.

The story is set in a royal castle where the selection process for the next crown princess is underway. Upon arriving, Therese finds herself surrounded by other young noblewomen who are eager to compete for the prince’s favor, and the competition is far more cutthroat than she anticipated. Her down-to-earth, practical attitude and desire to simply keep her head down and work become her greatest assets as she tries to avoid being dragged into the escalating drama and political feuds among the candidates.

Key characters include Therese herself, a pragmatic saver; her escort knight, Jade, who is assigned to protect her; and her attendant, Leina, who tutors her in the skills needed to become a lady-in-waiting. Other consort candidates, such as a noblewoman named Marietta, add to the intrigue and rivalry.

The narrative follows several notable arcs. After establishing her presence at the castle, Therese faces harassment from jealous noblewomen who barge into her room and bully her attendant, Leina. Despite her usual desire to avoid conflict, Therese fiercely defends her friend, demonstrating that even a penny-pinching candidate has her limits. Later, a mysterious event occurs when the prince gives roses to all the candidates. The roses slowly change color, leading Therese to suspect a hidden meaning behind the gift. Before she can solve the mystery, she suddenly goes missing during a tea party with Marietta, prompting a crisis that forces Jade and the prince to take action.
