The World Without My Sister Who Everyone Loved

After being taken in by the noble House of Nacht, Sienna grows up alongside her adopted sister Lorena, whom she believes to be the kindest and most loving person she has ever known. However, that illusion shatters when Lorena suddenly tries to kill her, revealing a deep-seated hatred she never suspected.

In desperation, Sienna attempts to end her own life using a magic potion, only to awaken once more—this time having traveled back in time. Determined not to repeat her tragic fate, she begins using her memories to survive and change the course of events.

Yet something is deeply wrong in this new timeline: Lorena, the very person who once defined her life, has completely disappeared without a trace.
