Yao Manning couldn't laugh; the anger in her heart had long since consumed all her reason.

But she still curled the corners of her lips and walked up to her, feigning concern, "Little sister, how have you been lately?"

"Mm." Yao Wanyin nodded.

Yao Manning turned to the doctors and nurses and said, "You can all leave now. I want to have a word with my sister alone."

Yao Wanyin was a little scared. She gripped the armrests of the wheelchair tightly, her lips trembling, but she dared not say anything.

After all, for the past twenty-odd years, Yao Manning has been the Yao family's daughter.

Yao Wanyin felt a pang of sadness.

I can only blame my own unhealthy body; I've been plagued by illness since birth and almost died several times.

Yao Zheng sought out renowned doctors everywhere, trying both traditional Chinese medicine and Western medicine, but the answers he received were all the same—

"The young lady's condition can be maintained with medication, but it cannot be completely cured, let alone allow her to live a normal life."

"Moreover, as she gets older, her condition may worsen, so you two should prepare in advance!"

However, Madam Yao was in poor health and could no longer have children. The Yao family needed a healthy daughter to secure a marriage alliance and to enhance the family's reputation.

Therefore, Madam Yao selected Yao Manning from the orphanage.

Not only because Yao Manning is healthy and lively, but also because her birth date and time are compatible with Yao Wanyin's.

A master once said that in order to save Yao Wanyin's life, she needed an older sister to bestow blessings upon her, ensuring her a worry-free life.

Whether it was true or not, Madam Yao believed it out of love for her daughter.

The couple has always treated Yao Manning like a daughter and raised her with great care.

As for Yao Wanyin, she has been bedridden for many years and rarely goes out, so much so that outsiders thought the Yao family only had one daughter and basically ignored Yao Wanyin's existence.

"Little sister." A cold glint flashed in Yao Manning's eyes. "I see your hair is messy. How about I comb it for you?"
