My Stepsister, My Strongest Ally - Episode 3

Cherry, the Jepsen heiress who was kept away for 18 years, returns and her parents announce a deal: Rudy will stay and the family will publicly recognize Cherry. They celebrate and plan a recognition party. A resentful sister, long overshadowed by Rudy, accuses Cherry of faking her identity and confronts others—"Why are you driving a wedge between me and Rudy?"—but is denied. At the party Bill Wild appears, first calling himself Rudy’s fiancé, then correcting himself as "the real Jepsen heiress' fiancé," a claim that shocks everyone and leaves loyalties unsettled.
