Duke Carhel Luave is known as the devilish duke due to his uncontrollable magical ability to charm every single person who lays their eyes on him. But this is more of a curse than a blessing with several noble houses plotting to drive him out of power. Having no one he can genuinely like or trust, Carhel wonders if he will ever be able to feel the warmth of another human being. One day, after raiding the estate of one of his enemies, Carhel mistakenly has Lena, the house’s maid, captured in the aftermath. But when he tries to use his charming powers to give her a painless death, something unexpected happens. For some reason, Carhel’s powers have no effect on Lena! (Source: Tappytoon)
