My Family Has a Younger Sister

[Blended family, childhood friends, growing-up romance]

Su Zhi was born poor. Her father died when she was young, and she lived with her mother and a tea merchant.

The tea merchant treated them terribly, often beating them. Only his son, Xie Wangchen, stood up for her.

Later, when the tea merchant fell gravely ill, her mother abandoned her and ran off with all the valuables she could carry.

Still very young, Su Zhi had no choice but to depend on Xie Wangchen. She tugged timidly at the boy's sleeve, looking pitiful and soft, her almond-shaped eyes brimming with tears as she called him “big brother.”

Everyone said Su Zhi had a hard life, but she never once complained.

Because her big brother doted on her, earning money to buy her peanut candy and gently carrying her to see the opera. He brought every beautiful thing in the world before her.

As time passed, she thought it was only natural and accepted it all without a second thought.

It wasn't until she sneaked out to play and spent the night at a married couple's home that she realized something was off:

The husband helped his wife put up her hair and shape her brows, then held her tenderly before the bronze mirror.

The husband helped his wife bathe and dress, gently wiping the water from the tips of her hair.

The husband and wife went to bed together, whispering and turning in each other's arms behind the curtains.

As she was taken back, she stared at her brother's hand, clenched so tightly it left red marks, and fell deep in thought.

The more Su Zhi thought about it, the more frightened she became. But when she looked at her gentle, intense big brother, she didn't dare say a word.

At last, she found a chance and ran away in a panic.

Xie Wangchen was cold by nature and ruthless in his methods. After his mother died, he grew to despise the whole world.

Then, beneath the warm spring sunshine, an innocent girl appeared before his eyes, following behind him and calling “big brother” again and again.

Her voice was sweet and charming, lilting and lovely, like a fledgling sparrow that made you want to protect her.

Warmth filled Xie Wangchen's heart. He gave her the only kindness and tenderness he had, and carefully raised her to adulthood.

He never imagined that the younger sister he'd raised with his own hands would run away without a shred of gratitude.

In an instant, Xie Wangchen's expression darkened, his gaze turned wild and resolute, and every trace of his gentle disguise disappeared.

When they met again, Su Zhi had become a young lady of the capital. She held the hand of a young man in white and smiled with carefree joy, as if she'd long since forgotten him.

Xie Wangchen showed no reaction. He politely exchanged greetings with the young man as his sister's friend and personally thanked him for looking after her.

But late that night, he took the fingers that had held another man's hand and wiped them clean one by one.

Then he shed every trace of restraint and refinement, took her hand, placed it on his sash, and slowly stroked and explored it.

“Azhi, I raised you. There are many things you don't need anyone else for.”

“Your big brother will teach you himself.”
