After she wakes up from being reborn, she becomes the little pitiful girl who is sent into a mental hospital by her biological elder brothers. Her biological elder brothers only dote on the fake young miss, the ‘younger sister’ who is switched at birth. She despises her in any possible way. So, Pei Yunge makes trouble and deals with the fake young miss, waiting for them to tell her to scram. However, the brothers’ attitudes are extremely strange. 
President Qin sneers. “My younger sister destroyed a shop? Buy the entire mall for my younger sister to trash!”
Best Actor Qin raises an eyebrow. “She sent herself to the casting couch? What am I then, dead?”

He was not sure if Pei Yunge could accept a more noisy place.

"Go ahead. I'll try something else."

With that said, Qin Yu nodded. With the production team around, he was not afraid that something would happen to Pei Yunge.

Seeing Qin Yu leave, the people started to give advice in the comments section.

[I knew it. Brother Yu must have planned it.]

[There are three sisters, but why is Pei Yunge the most burdensome…]

[I'm really going to stop being a fan because of the celebrity's family for the first time.]

[Just watch. When the time comes, she will definitely sit there and enjoy the breeze. When Qin Yu returns after singing, she will take the money with a clear conscience.]
