[Reincarnated into a novel I loved when I was alive.] Too cliché, you say? Think again! Because that novel… is a 19+ dark fantasy story! Reinatis is reborn as the younger sister of the beautiful and kind female lead, but when she can't bear to watch her sister suffer a tragic ending, she takes her place— and ends up captured by the insanely handsome and utterly mad male lead, Theodore. But wait... this guy... he's just an madman, isn't he?! "Okay, sure, I do have a thing for beastly men… but I wasn’t asking for an actual beast!" Thus begins the tale of mc brighter than sunlight… taming her beast (of a man).
