Lady Zara of Eternal Peace was born noble, intelligent, and a master strategic planner. She wanted to give birth to an heir for the royal fiefdom as soon as possible, so she chose a seemingly honest Third-Class Imperial Scholar as her fiancé, and paved the way for his career advancement. However, as soon as his official career began to take off, he planned to take an Equal-Rank Consort on their wedding day. She decisively broke off the engagement with the Third-Class Imperial Scholar, and chose Vincent Windsor, known as the most dissolute playboy in the capital, as her husband, only to discover that beneath his dissolute facade, Vincent hid many secrets.
