A little sister's tears are more precious than pearls.
Gentle, fiercely protective older brother X super-dependent, sweet younger sister
1.
Shen Wanyu came to live with the Zhou family when she was four.
Zhou Yuanqing was two years older than her, and they grew up together.
At the age when he was first falling in love, his favorite thing to do was watch Shen Wanyu play. He could watch her for hours.
Shen Wanyu knew her brother liked to stare at her, so she would put on pretty dresses and play where he could see her.
When Uncle and Auntie weren't around, she would sneak into her brother's room.
Zhou Yuanqing would lie on his side, gazing at her in silence.
Shen Wanyu would scoot closer until their two fuzzy heads were side by side, then whisper, "Brother, will we still live together when we're grown up?"
2.
High school graduation.
Shen Wanyu went to the city where Zhou Yuanqing was studying to spend the holidays.
He was no longer satisfied with simply watching her in silence.
In the sweltering summer, they began holding hands and embracing.
Here, no one knew that Shen Wanyu was the little sister who had grown up with him.
His love and possessiveness grew at a furious rate.
At the end of August, the holiday was about to end.
One night, Shen Wanyu opened Zhou Yuanqing's door and slept beside him, just as she had when they were children.
Only this time, they were both adults.
The next day.
Zhou Yuanqing held Shen Wanyu from behind. They were laughing and kissing as they opened the bedroom door, only to see Uncle Zhou and Aunt Zhou standing there, utterly shocked.

Years later, the Zhou family arranged a good marriage for Shen Wanyu. Everyone in Jiangcheng praised the Zhou family for being so generous and caring so much even for an adopted daughter.
Shen Wanyu sat in her brother's childhood room and cried for a long time.
At the engagement party, a private plane landed on the Zhou family's runway.
Zhou Yuanqing, who had been exiled abroad, ignored everyone trying to stop him and showed up in person. Handsome and aloof, he drew everyone's attention.
When his parents questioned him, he replied politely and humbly, "My little sister is getting engaged. Why didn't you tell me, her older brother?"
His parents: Who gave you permission to come back to the country!
After seeing Shen Wanyu's fiance, Zhou Yuanqing walked up and yanked off the man's tie.
He casually straightened his own bow tie and smiled warmly. "Welcome to the engagement party for my little sister and me. What should I call you?"
The fiance looked furious. "What did you say?"
Shen Wanyu was forced to change into a red qipao for the engagement party. Her fair little face was bare of makeup, her eyes red and lips pursed as she was led to the lawn where the party was being held.
Both leads are virgins.
The male and female leads aren't on the same household register, and it isn't a formal foster arrangement.
