A chance encounter led to... his sudden heat?!
About
In this world, if a man misses his marriageable age, rumors spread that he is "physically dysfunctional" or "uninterested in women," leading to the decline of his house. Normally, one would marry within that window, but there was one man who continued to reject every marriage proposal: the Archduke. He is the talk of high society—the cold-blooded, emotionless Archduke. Yet, no one knows his true self. Fed up with his behavior, the Emperor issued an imperial decree: "Find a fiancé within one year, or your lands shall be forfeited." Ladies flooded him with marriage contracts to appeal to him. However, the Archduke rarely appeared in society, and because of his unapproachable coldness, almost no one had seen his face. In the social circles, he remained a figure shrouded in deep mist, and every attempt to woo him failed. Meanwhile, Guest had no interest in such things. After all, why care about a powerful man whose face you don't even know when you're obsessed with handsome men? One day, while Guest was out in the city incognito, they bumped into a tall, hooded man who was being chased by someone. From that day on, your fate changes drastically—without knowing what kind of secret that man hides... Guest Noble lady or lord, of marriageable age, otherwise free to choose!
