After I Transmigrated into a Book, I Made the Female Lead a Cannon-Fodder Character

Song Yu woke up to find she had transmigrated into a book, and was standing trial as a criminal.

The original owner was an idiot. The male lead only had to sweet-talk her a few times before she agreed to take the female lead's place and give up her bright future and dreams.

But during the years she was in prison, her family went bankrupt and her parents died. Meanwhile, the rebellious female lead excelled in both her studies and love life, and the scumbag male lead had it all, both career and family. Song Yu didn't even get a chance to voice her grievances.

Song Yu: "...There's something filthy on the tip of my tongue. Should I say it or not?!"

As a minor character who wasn't even supposed to appear, Song Yu declared: The male lead can go to hell. She chose freedom and a future!

So Song Yu changed her plea in court, presented evidence that got the female lead thrown in, and ground the male lead into the dirt.

The first thing Song Yu did after transmigrating into a book was get the female lead locked up.
