Yan Mingzhi was born into a wealthy family. Sheltered by her eldest brother, she grew up in luxury, spending lavishly and acting spoiled and adorable.

Then an anonymous paternity test arrived, stating in plain terms that she was not biologically related to her father.

The mansion and designer brands all turned out to be a beautiful dream. The person she had so freely depended on wasn't her biological older brother. Yan Mingzhi was frantic. She didn't want to live in poverty. She didn't want to be a little orphan without a brother!

Her eldest brother, already a director in the family conglomerate, tapped her on the head and said warmly, "Mingzhi, if money can solve it, it's not a problem." Then, without asking why, he gave her 100 million. Once things were settled, Yan Mingzhi kept her secret and continued spending her brother's money like water.

After their grandfather died, the family tore itself apart, and the brothers turned against each other. The warmth of the past had all been an illusion. Only her eldest brother remained as refined and noble as ever, disdainful of their dirty tactics and always protecting her.

Yan Mingzhi chose to stand by him without hesitation and swore never to betray him.

Her eldest brother hugged her gently, his exhausted voice tugging at the heartstrings. "Thank goodness I still have little sister Mingzhi as family."

The inheritance battle ended, and her eldest brother became the head of the century-old family, the new master of Hong Kong's luxury industry.

Yan Mingzhi's identity as a fake heiress was exposed, but her eldest brother didn't care at all. Wealth, status, and rare treasures continued to pile up around her.

Yan Mingzhi's lavish lifestyle was completely unaffected. She only occasionally lamented that she and her eldest brother were now the only ones left in this extravagant century-old manor.

But those fallen family members kept coming back, telling her about a side of her eldest brother she had never seen.

Second Brother: He was the first person to find out who you really were.

Third Sister: You're the only one that lunatic considers family.

Fourth Brother: He thinks we're dirty? His methods were the dirtiest of all when he drove us out.

Their father slapped his eldest brother, making his face turn to the side. "You beast! Even if she's not your biological sister, she grew up with you!"

Yan Mingjue wiped the blood from the corner of his mouth. His gaze was no longer warm and refined, but dark and twisted. "You found out, then insisted on making her leave me."

The doctor said Yan Mingjue was ill: depression and anxiety caused by psychological trauma. The best treatment would be to have his family stay with him.

Yan Mingjue replied, "My wife is very sweet and stays with me every day. I'm recovering well."

His only family was his younger sister. Since his sister was family and his wife was family too, his sister was his wife.

As he said this, Yan Mingjue's fingers trembled. Restlessness churned in his chest and his addiction grew wilder. He had to hold Yan Mingzhi immediately.

The doctor looked horrified and shook his head frantically. No, your condition seems to have gotten worse.

"No one can come between us. Not even Father."

"He's addicted to his little sister. He can't quit anymore."

In the vast, magnificent manor, only two other people lived with her:

One was the brother who loved her, and the other was the pervert who loved her.
