What Should I Do After I Transmigrate into a Book and Become Utterly Ordinary?

When other people transmigrate into a book, they get a System or a personal space. At the very least, they can become a beautiful supporting female character.

Tu Nan, on the other hand, was a perfectly good rich beauty who transmigrated into an ugly duckling. The heroine and supporting heroine enter the entertainment industry one after another and fight so fiercely that the heavens and earth are turned upside down, while she's merely an [unnamed college classmate of the heroine]?

No way. She won't let that happen.

But before she makes trouble... Looking at her utterly ordinary face and reviewing the original owner's utterly unremarkable life, Tu Nan decides to get double eyelid surgery first.

P.S. The face described as utterly ordinary really is utterly ordinary. No System, no personal space, no lucky encounters. Everything relies on modern medical procedures. This is a story that may include, but isn't limited to, minor cosmetic surgery, medical aesthetics, makeup, skincare, game streaming, and taking entrance exams for a graduate program in a different field. Our goal: to become a woman with both beauty and brains!
