[ENG DUB] My Stepsister, My Strongest Ally - Episode 6

Mason confesses he’s liked Rudy since childhood, but Rudy and others call him a liar, blaming him for pranks. Mason insists he's sincere, threatens to involve their grandfather and produces tape as proof. Mr. Jepsen and relatives argue over Rudy’s status—not an heiress or birth daughter—until someone declares "Rudy is still our daughter" and the family reunites. Mason says he came to check on her, then loudly vows to "wait" through engagement, annulment, divorce or widowhood. The episode ends with Zane declaring he's set on Rudy and rushing after her while Mason’s vow lingers unresolved.
