Transmigrate into a Book: The Lucky Star and Her Foil in the 1970s

After transmigrating, Shen Fu discovers that she's become the unlucky contrast character to the lucky heroine in a period novel.

As a character meant to highlight the heroine's kindness and beauty, Shen Fu is supposed to be foolish, wicked, and brainless. Shen Fu wants to die again right away. Luckily, the transmigration gods still have a conscience and give her a golden finger. The plot is almost over, too, so Shen Fu can still be herself.

Then she'll live her life well, deal with the awful people while she's at it, expose the lucky heroine for who she really is, and enjoy this rare transmigration experience.
