Light and Dark

Everyone knows that any unsuccessful girl who finds herself in another world always becomes the owner of the body of the smartest, most beautiful, and strongest person. In a word, the best of the best. And then the entire world, along with a magnificent beloved, is at her feet. But what to do if she finds herself in the body of a long-since and definitively insane Light, who is also married off to a harsh and ruthless Dark Mage? Of course, she must look for the bright sides in the dark soul of her sinister husband. After all, even the Mage of Death wants to be happy and will not mind a reasonable and devoted wife.
