My Little Sister Stole My Fiancé, and Now I've Been Forced to Marry the Hideous Duke @COMIC

Raised harshly and subjected to relentless mistreatment since childhood, Lucrezia has weathered every cruelty by convincing herself that each hardship was simply another trial born of love. That unshakable optimism has carried her through everything—so when her father orders her to marry a man of the worst possible reputation, the notorious "Hideous Duke," she resolves to overcome this newest "enjoyable trial" as well. Smiling all the while, she sets off to meet the infamous Lamirio, determined to conquer whatever awaits her. Yet the man who comes out to greet her bears no resemblance whatsoever to the grotesque figure of the outlandish rumors. Instead, Lucrezia finds herself drawn to Lamirio's courteous manner and thoughtful care. Just as her heart begins to stir, however, he delivers a startling declaration: there will be no engagement, and for the time being she is to devote herself entirely to rest and recuperation—? What Lucrezia doesn't realize is that Lamirio harbors suspicions of his own. A lady as beautiful as her, arriving and all but pressing him for marriage? To his mind, the whole situation seems far too good to be true—and he can't help but wonder whether he is the target of an elaborate marriage scam!
