Substitute Wife? I Married His Worst Enemy

“Madelynn devoted three years to Isaac, only to be discarded the moment his first love returned. Realizing she had been nothing more than a substitute, she walked away without regret. Everyone expected her life to fall apart, until her hidden identities shocked the world. The legendary mentor behind countless prodigies, a woman admired by global elites, and someone even powerful leaders sought, she was far beyond Isaac's reach. As Isaac desperately begged for another chance, Madelynn married his greatest rival Dominick instead, leaving him with nothing but endless regret and unanswered longing. Madelynn rolled her eyes. "Please. Stop flattering yourself. Dominick is my darling, my sweetheart, my one true love!" Isaac cornered her, jealousy burning in his eyes. "Madelynn, you're only doing this to get under my skin. You still care about me."”
