After I Transmigrated into a Book, I Only Wanted to Break Off My Engagement to the Hero

She accidentally transmigrates into a book and becomes a brainless cannon-fodder supporting character!

With no memories of the original owner and no System to help her, she has to break off her engagement to the male lead if she wants to survive to the end of the story.

So she does everything she can to stay away from him and fade into the background!

What she never expected was that the villainous second male lead, also a fellow cannon-fodder, would keep flirting with her from time to time, making her heart flutter!
