【Book and Manga Adaptation in Progress】 'I have always been neglected by my father. Even when my fiancé was taken by my sister, he did not help me but instead ordered me to marry the man known as the “Ugly Duke,” who has the worst reputation. Oh, how exciting it sounds!' From a young age, Luchretia had been mistreated, and she saw this as a test of love, applying a misguided positive mindset. She set off to the Ugly Duke’s place as commanded. However, the man who welcomed her was nothing like the amusing rumors suggested, and he seemed strange. '—Oh? This man doesn’t seem to be ugly at all, does he?' Expecting a series of challenging tests, she found none. The “Ugly Duke” had returned to his true form, and everything was nothing but happiness. Meanwhile, Luchretia’s family and ex-fiancé realized too late how important she had been, but it was already too late, and the kingdom was on the path to destruction.
