Synopsis: The World Without My Sister Who Everyone Loved

"I despise you enough to want to end your life, Sienna." I lived in the shadow of my sister and was ultimately betrayed by her, leading to my demise. However, upon returning to the past, I have noticed a shift in people's behavior. "You are the sole offspring chosen by Nacht." "His Highness regards you as kin." Something is amiss as these individuals appear to confuse me with my elder sibling. "Please trust that we genuinely care for you." I once yearned for affection, but now I fear that this sentiment may be my downfall. One act of betrayal suffices. Placing one's entire being into love ultimately ends in ruin. All I desire is to reclaim the life I once had.
