The Fake Saintess Just Wants to Take It Easy, but the Real Saintess Won’t Let Her

[Women's fiction, Western fantasy, two female leads, no male lead, not a powerful heroine! Lazy, silly beauty VS gentle wolf in sheep's clothing] The gods deliver a prophecy: a daughter of the Zangweiler family will become the Saintess of Light. Unfortunately, Elilo is a fake heiress. She prays at the Temple of Light, and divine punishment descends. And then... Elilo kicks the bucket. She is reborn three years earlier. Elilo decides to find the real heiress ahead of time and have her clean up her mess. But her sister, Peici, doesn't believe a word she says. Elilo: “Little sister, I'm hardworking, brave, and good at cooking. Come home with me!” Peici: “?? Are you trying to kidnap me?” Elilo: “Little sister, this family needs you. I can't live without you!” Peici: “The future Saintess... needs me? What a good person~” Peici (clenching her fist): “Don't worry! I'll work hard to become a knight and protect Your Highness!” Elilo: “Can someone please save me? I'm just trying to stay alive ฅ(๑ ̀ㅅ ́๑)ฅ Hey!” * When Peici sees the future Saintess walking toward her, she realizes that she really is a wonderful person. Having grown up in the rough, seedy streets, Peici has already learned to do whatever it takes. She knows her true origins and wants to take Elilo's place, yet she can't help but cherish Elilo's kindness. She's starting to feel reluctant to hurt her. After all, what did Elilo ever do wrong? In that case, I'll stay by her side and become her knight, Peici thinks, satisfied.
