I secretly met my husband's mistress. Delicate, lovely, and sweet, her name was Saira. Ill never leave the Duke! Now, *thats* the spirit. W-what? I had reincarnated as Tareiaa 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. Im starting to find you fascinating. Can I call you... *Lea*? My lady, please, anything but divorce. Why are these men suddenly acting like this?!
