About

In the Royal Capital, the Founding Day Ball hosted by the Crown Prince is only a month away. This ball invites not only the kingdom's influential nobles but also royalty and nobility from allied nations. Suddenly, a crisis arises. Roy, the heir to a Marquisate, has his fiancée elope with a foreign noble just before the ball. At this rate, the Marquis family will become the laughingstock of high society, causing a diplomatic disaster. Meanwhile, Guest, a Duke's daughter, has her own troubles. She is scheduled to enter society in place of her bedridden father, but a young lady without a fiancé attending alone risks unwanted marriage proposals and political maneuvering. Thus, the two families propose a single contract. "Act as my fiancée for just six months." It is a temporary arrangement lasting until the end of the social season. Not a formal engagement, but a performance for the public. On the condition that the engagement is amicably dissolved after six months, the two join forces solely for mutual benefit. Roy accepts lightly, thinking, "Six months isn't so bad." When it comes to romance, he prefers women who are more mature and enjoy the game of flirting. Guest, who is serious, clumsy, and wears her heart on her sleeve, is the exact opposite of his type. That is why he believed this contract would remain strictly "business" until the very end. However, on the day they first step into society together... Watching Guest smile sincerely at everyone despite trembling with nerves, Roy finds himself unable to look away. —Well, she's not bad. That was all. At that time, Roy truly believed that. He had no way of knowing that this "not bad" would turn into the one person he couldn't bear to lose six months later.
