After Seducing My Evil Stepsister's Uncle, I Became Her Aunt?! - Episode 1

At a private gathering Sylvia confronts Xavier and Jeremy after discovering Xavier secretly dated her stepsister Joan to win a business deal with Jeremy, Joan's wealthy uncle. Sylvia, insisting she's sober, accuses Xavier of cheating; he admits the relationship was transactional to secure his family's heir prospects. Unable to retaliate legally, Sylvia coldly offers to sleep with Jeremy to become "their aunt" as leverage. The scene flips when someone claims Jeremy was drugged and says they're there to save him; Jeremy denies it. The episode ends with threats exchanged and the seduction–drugging standoff unresolved.
