Delicate, lovely, and sweet, her name was Saira. “I’ll never leave the Duke!” “Now, *that’s* the spirit.” “W-what?” I had reincarnated as Tareia—a noblewoman with a wealthy family, beauty, and nothing to feel inferior about in life. But there was just one obstacle in my perfect plan: “Keep seducing my husband.” I was ready to toss him aside and live a fabulous single life. ...Or so I thought. “I’m starting to find you fascinating.” “Can I call you... 'Lea'?” “My lady, please, anything but divorce.” Why are these men suddenly acting like this?! --- Watching on helplessly as her beloved husband carried on a whirlwind affair with a beautiful commoner, then dying tragically only to be replaced right away by that same mistress, Duchess DeLov was a pitiful figure... in the book I didn't even bother finishing!
