Leisha, a countess, is constantly burdened with dark circles under her eyes, her appearance neglected due to her responsibilities. In contrast, her stepmother's daughter, despite a commoner parent, is beautiful and charming, leading to Leisha being ridiculed in society. Unexpectedly, Leisha receives a marriage proposal from the handsome but serious Duke Lindbeld. The Duke, while not wanting to marry, seeks a wife who won't interfere with his work or personal life—a wife in name only. Leisha, uninterested in the Duke, is chosen. She proposes a condition: three meals, a nap, and a minimum standard of living in exchange for marriage. This is because Leisha has been overworked and sleep-deprived, juggling her irresponsible father's work and her stepmother's duties. This marriage offers her freedom from her exhausting life. The story features a relaxed setting and a slow-burn romance.
