Darling, Why Do You Regret It？

I secretly met my husband's mistress. 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?!
