One hundred million dollars, I'm buying your life!" The female lead raises an eyebrow and chuckles. The cute baby in her arms winks—the mother and son share a perfect understanding. "Mr. Ethan, a buy-one-get-one deal is too shabby. I'm even giving you my genius son, who can hack your group's system. Are you sure you don't want to reconsider the price?"
