Yes, although Wen Qingyu had a miserable and distressing life, which made the hearts of readers ache for her, she was not considered a tragic character. On the contrary, her existence was healing and therapeutic. She became an iconic character, not because she was remembered through death, but because of her talent in creating works, and her ability to eat books like it was food...
Zhao Youyue could not help but add something to Wen Qingyu. This new setting was so that whenever she eats a book, she would be able to remember it completely. This was equivalent to the ability to read books and never forget them. If she had such an ability in the real world, it would be great.
When Zhao Youyue had nothing to do, she could just casually eat some books; then she would probably be able to get a nickname like "walking library."
