He’s My Real Brother, Duke

In a fantasy novel, I possessed the hidden younger sister of the Male Lead, ‘Astel’. While my brother Cassian is struggling for the revenge of the family, it’s my job to find and deal with the final Villain that has not been revealed even at the end of the original novel!!! In order to do that, I must first enter the Northern Duke Castle, where the family’s traitors are hiding. Somehow, I became an “imprint of companion” of Duke Anais, a beast of beast and a leading candidate for the final villain. Besides…… “Please kiss me now, Astel.” In order to live, you’re required to have a daily skinship with your ‘imprint partner’. There was no such thing in the contents of the original story...
