This story became the most popular on the Shōsetsuka ni Narō platform, ranking #1 overall in January 2024, and now it’s finally getting a manga adaptation! Everyone sees my sister as a “blessed saint”—spending her time in church, doing charity work, and earning the love of all. But to me, she’s more like a “hidden devil.” Because of her, our family is constantly struggling financially—every bit of money I save, she donates to the church without a second thought! As time passes, things only get worse, until one day, a handsome man from the kingdom arrives, searching for the true saint. Without hesitation, I see this as my golden opportunity, so I quickly say: “Oh, that’s my sister! Take her with you right away—no need to wait!” But... will this be my true salvation, or the beginning of an even bigger problem?
