My Family Heard My Thoughts, While I Chilled, Snacked, and Watched the Show

Transmigrating into a book with dual Systems, adored by the whole family + wealthy-family business rivalries + comedy (a cannon-fodder character transmigrates into a book + the whole family can hear her thoughts, absurd rants and face-slapping, powerful characters collectively break character)

On the very first day after transmigrating into a book as a fake heiress from a wealthy family, I'm told I have to finish playing the villainess role before I can go home.

At the homecoming banquet, my adoptive father tries to force me to give up my inheritance. I rant furiously in my head:

[I'm dying. This old man wants me to give up my shares, but he has no idea that in three days his business partner will cheat him out of everything, and he'll be so furious he'll have a stroke and be paralyzed.]

My adoptive father, who was about to explode, goes deathly pale and calls off the deal that very night.

But my family starts to wonder if their spoiled, willful daughter is acting a little strange.

My actor big brother is framed by a scheming green tea, and faces a huge breach-of-contract penalty?

I sigh inwardly: [Poor big brother, that woman has him completely fooled. The baby she's carrying is actually his sworn enemy's!]

My big brother takes the green tea straight for a paternity test.

My top-tier star second brother is exposed for throwing his weight around, putting his career in jeopardy?

I shake my head inwardly: [You fool, Second Brother! Your assistant was bought off ages ago, and the recorder is in his pocket. If you don't get the evidence now, it'll be destroyed!]

My second brother immediately pins his assistant against the wall.

Later, I realize that someone keeps inexplicably stealing credit for my good deeds. Then one day, I run into the great villain who was supposed to kill my entire family in the book.

Alarm bells ring in my head as I point at Li Beixiao, the future tyrant of the wealthy world, and glare at him.

[So it's you! You've been eavesdropping on my thoughts and stealing my credit all along!]

Li Beixiao: ???
