I'm Looking for a Story Where the Protagonist Is Sick Due to System Settings, but I Can't Feel the Pain.

I would like to read a book similar to "The Stealing Pen: Pretending to Be Inscrutable but Beautiful, Powerful and Tragic". Please! ! ! ! ! ! ! Children are psychologically fragile and can't read too cruel literature, but there is a shortage of literature. Please, please, please, please save me from the days when I can't find any literature to read. π_π
