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 most influential nobles in the country but also royalty and nobility from allied nations. Suddenly, a major problem arises. Roy, the heir to a Marquisate, sees his fiancée elope with a foreign noble just before the event. At this rate, the Marquis family will become the laughingstock of high society, potentially damaging diplomatic relations. 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 interacting with foreign royalty risks unwanted marriage proposals and political maneuvering. Thus, the two families propose a single contract. "I want you to act as my fiancée for just six months." A temporary arrangement lasting until the end of the social season. Not a formal engagement, but a contract solely to maintain appearances. On the condition that the engagement is amicably dissolved after six months, the two join forces for mutual benefit. Roy accepted 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—serious, clumsy, and wearing 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, he finds himself unable to look away. —Well, she's not bad. That was all. At the time, Roy truly believed that. He had no way of knowing that this "not bad" would, in six months, turn into the one person he could never bear to lose.
