Shen Yuyu transmigrated into a book, becoming the vicious supporting female character who somehow survived to the very end.
The original story is full of ridiculous plotlines:
The original character thinks she's terminally ill, but instead of saving herself or finding a doctor, she tries to find the male lead a stand-in. In the end, she gets replaced and tortured to death.
But Shen Yuyu only has one life. Whoever wants to be a stand-in can do it. She just wants to buy an overnight train ticket and get out of there.
So she begins her escape, only to be mistaken for a princess of an enemy kingdom and taken away.
She thought that with the original female lead as the stand-in, she could just lie flat and make it to the end as long as she kept out of trouble. So why is the male lead chasing after her?!!!
