The aristocratic Lu family has produced a joke, a beautiful one, but a joke nonetheless. The daughter they have been rearing all this while turns out to be an imposter! With the real heiress returning to take her rightful place, everyone is eager to know the outcome of the imposter...
Will she be able to survive in poverty after living a life of riches?
Having just transmigrated, Huo Yao imagines that this experience will be pretty interesting. However, imagination and reality are always so different! 
Dad: "Daughter! Take this black card. It has no limit! Use it freely."
Mom: "My dear Yao Yao! If you don't like this jewelry, I'll get them to change it immediately."
Huo Yao: "…"
Weren't they supposed to be poor and ordinary? What is with this hidden lavish behavior?
Her eldest brother, an investment company's CEO: "Sis, inherit my company!"
Her second brother, a top lawyer: "Whoever dares slander my sis will face the full brunt of the law!"
The third brother, an international genius doctor: "Bullying my sister? Should I display the prowess of my scalpel?"
Mysterious fourth brother: "My sis is the cutest!"
Huo Yao: "…"
What happened to being a good-for-nothing person who lives off her parents?

Everyone who knows about it, doesn't dare say it out loud. 
All they can do is curse inwardly: "Bah! Keep acting! No one believes it!"

Transmigrated As the Fake Heiress

Huo Yao failed to detect the strange look on the old lady's face. Her phone rang at that moment and she retrieved it from her pocket to see that it was her second older brother calling.

Huo Yao looked at her grandmother and said, "Oh yes, Grandma. My second older brother is here to visit you and is waiting downstairs now."

The moment the old lady heard Huo Yao, the sad look on her face was swiftly replaced with shock.

Then she composed herself and said, "Is it your biological second older brother? Hurry up and bring him over."

"Mhm," replied Huo Yao. Huo Yao noticed how flustered the old lady was looking.

She patted and straightened her short hair. Huo Yao saw this and could not help teasing her. "Grandma, there's no need to be nervous. He's family."

The moment her grandmother heard this, she put down her hand somewhat shyly as she said, "It's the first time I'm seeing him, so I want to leave a good impression."
