Zhao Mianmian transmigrated into a sweet romance novel set in space, becoming the real daughter who was switched at birth, and ultimately ended up being torn apart alive by the Zerg.

Transmigrating into a book is scary, but being a female supporting character is even scarier. She has biased parents who dote on the fake heiress, and her older and younger brothers who also favor the fake heiress. Her fiancé treats her like a virus.

After transmigrating into a book, Zhao Mianmian had to kick her parents to the curb, abuse her brothers and trample on her fiancé, embarking on a solo interstellar farming journey, and even more inadvertently seducing an interstellar tycoon down from his pedestal.
