I'm an Elite Angel, But I'm Troubled By an Impregnable High School Girl

I’m an elite angel, but there’s one high school girl who’s giving me a real headache. Our job as angels is to assess people’s good deeds and grant them the little wishes hidden within those acts. I’m Ariel, and I take my duties seriously. But then I met this girl—she’s done countless good things, yet there’s not a single small wish for me to fulfill. How is that even possible? She’s completely stumped me.
