Akuyaku Reijou to Kichiku Kishi

Her engagement is broken off, the heroine is harassing her, and she's forced to work in a brothel! To make matters worse, her first customer is none other than the heroine's childhood friend and debauched leader of the Imperial Guard, Duke Lucas Herbst. Terrified, Cecilia shares an intense night with him, only to wake up the next day in his mansion—marked as his fiancée?! Bound to this unhinged knight, the troubled villainess must endure his obsessive love. But is his intoxicating affection a curse... or is it a blessing in disguise?
