Shoujo Manhwa with unique ML personality. Not your usual cold Duke type, or so obsessed With FL early in the story, I don't want Harem. I also don't like ML that so obsessed to FL that treated everyone like. Shit, or that ML that so rude to FL at first or hated her cuz of her "Reputation" for being a Villainess.
