After My Sister Died, I, Who Was Born Evil, Went Crazy.

Why Is It That During the Day, There Are No Books to Read, and Only at Night Can I Find What I Am Interested In?

Please recommend, Shuangnan. No matter what type it is. There is a shortage of books during the day, and I can't find an interesting book... Is there any curse during the day? Especially in the morning, I can't find a book at all...
