Dressed as a Female Counterpart: Does the Crow's Mouth Also Have Kpis?

[Wearing a book + female supporting character + system + overhead + 1v1] Ye Wuya had just paid off her mortgage and wanted to read a novel to relax before going to bed. When she woke up, she unexpectedly transformed into the frail and sick female supporting character in the book. She died before the ending! Ye Wanya felt miserable. She had been working hard for the first half of her life to pay off the mortgage. Why did she slip into the book before the bed was warmed, and she was dressed as a cannon fodder female supporting character who would not survive the end? When Ye Wuya entered the book, he was also bound to the crow's mouth system. As the name suggests, bad words will become reality, and he must crow's mouth at least once a day, otherwise he will be wiped out by the system. Ye Wuya secretly sighed: How could there be such an unlucky person as him? No matter what, the top priority is to survive first, and then find a way to return to reality. But can we go back?
