After being taken in by the noble House of Nacht, Sienna grows up believing her adopted sister Lorena to be gentle, loving, and kind. That illusion shatters when Lorena attempts to murder her, revealing years of hidden hatred beneath her smile. Despairing and betrayed, Sienna drinks a magical potion to end her life—only to awaken in the past instead. Given a second chance, she resolves to survive by using her memories to avoid her tragic fate. But when she searches for the sister who once tried to kill her, Sienna discovers something far more unsettling: Lorena has completely disappeared from this timeline. As the past unravels differently than before, Sienna must uncover the truth while protecting herself from a future she no longer understands.
A World Without You excels at psychological unease. Rather than offering immediate revenge, it replaces certainty with doubt—forcing both Sienna and the reader to question what was real, what was misunderstood, and what dangers still lie ahead.
Sienna’s strength comes from awareness rather than power. Her trauma informs every decision, making her cautious, observant, and deeply human. The absence of Lorena transforms the story from simple revenge into a mystery about identity, obsession, and fate itself.
This webtoon is ideal for readers who enjoy dark fantasy regressions, emotionally complex female leads, and stories where the past refuses to behave as expected. A World Without You isn’t about fixing the timeline—it’s about surviving it.
