The Poor Daughter They Ignored Was Actually a Billionaire

My family thinks I’m a broke clinic receptionist who never finished college. At my sister’s billionaire wedding, they humiliate me, try to match me with unwanted men, and finally throw me out. But just as I turn to leave, the groom’s billionaire grandfather rushes in and begs me to stay. Then everyone learns the truth: I’m a famous cancer researcher, a biotech founder, and a secret billionaire whose patent could save the Sterling family’s billion-dollar drug project.
