[ENG DUB] My Stepsister, My Strongest Ally - Episode 9

At Cherry Jepsen's recognition party someone accidentally ruins her dress, sparking immediate accusations that Rudy is responsible. Guests split: some defend Rudy's intelligence and deny she'd use such tricks, while others mock Cherry's gown as cheap. Conversation shifts to appearances—Rudy's clearly couture, Cherry's a regular design—and reminders that Rudy has lived with the Jepsens for 18 years feed the comparison. The celebration unravels into a family dispute as Rudy continues to steal the spotlight. Cherry can't swallow her parents' apparent favoritism, leaving the party fractured and loyalties unresolved.
