Synopsis: If You Are Looking for a Saint, It Is Definitely My Younger Sister. Please Take Her Away, Right Now

My sister goes to church every day and gives energetically to charity, and everyone praises her, saying that she must be a saint. But thanks to her donations, our family's finances are always on fire. My sister donated all the money I had saved to the church. Then a beautiful man appeared and said that he was a messenger from the kingdom looking for a saint. Please, by all means, take my sister now!
