Oops, You Bullied the Billionaire's Wife

Yvette is a scientist and the wife of Graham, the richest man in H Nation. She spent years in the Antarctic working on the life enzyme, a treatment for rare diseases, and the conditions there cost her the ability to have children. During her absence Graham adopted three children from an orphanage and raised them, intending that Yvette would choose an heir to the group when she came back. Yvette flies home quietly, carrying the life enzyme. The three adopted children are at the airport waiting for her. They do not recognize her, take her for a poor stranger passing through, and abuse and humiliate her there in front of everyone.
