The Nameless Billionaire: My Ex-Wife's Regret.

Three years of humilation. Three years of being a "worthless" student and a stray dog in the Hawthorne family. Ethan Kaelen endured it all to satisfy a secret family trial. But on the day he was ready to give his wife the world, she gave him divorce papers and a mouthful of spit. "A beggar doesn't deserve a queen, Ethan. My new man is a real Kaelen heir." She dumped a God to chase a fraud. Now, the trial is over. The Sovereign System is online. Ethan is putting back on the emerald ring that controls half the world’s wealth. He’s done being the nice guy. Elara wanted a billionaire? He’ll show her what a real one looks like. By the time he’s finished, she won’t just be crying; she’ll be begging to even be his maid.
